A quick snap for some discussions on my '2nd backup' kit and configs. The main setup is the top left of EOSM, 11-22mm ultra wide, E2 GPS unit and Finder/Scope attached to the back. The other shots are using the EF adapter with some of my Canon 5D3 lenses on. The Rokinon 8mm is interesting as it gives a very useful full frame 12mm lens with moderate distortion

The Supermarine Spitfire is a British single-seat fighter aircraft that was used by the Royal Air Force and many other Allied countries during and after the Second World War. The Spitfire was built in many variants, using several wing configurations, and was produced in greater numbers than any other British aircraft. It was also the only British fighter to be in continuous production throughout the war. The Spitfire continues to be a popular aircraft, with approximately 55 Spitfires being airworthy, while many more are static exhibits in aviation museums all over the world.
The Spitfire was designed as a short-range, high-performance interceptor aircraft by R. J. Mitchell, chief designer at Supermarine Aviation Works (which operated as a subsidiary of Vickers-Armstrong from 1928). In accordance with its role as an interceptor, Mitchell designed the Spitfire's distinctive elliptical wing to have the thinnest possible cross-section; this thin wing enabled the Spitfire to have a higher top speed than several contemporary fighters, including the Hawker Hurricane. Mitchell continued to refine the design until his death from cancer in 1937, whereupon his colleague Joseph Smith took over as chief designer, overseeing the development of the Spitfire through its multitude of variants.
During the Battle of Britain (July–October 1940), the Spitfire was perceived by the public to be the RAF fighter, though the more numerous Hawker Hurricane shouldered a greater proportion of the burden against the Luftwaffe. However, because of its higher performance, Spitfire units had a lower attrition rate and a higher victory-to-loss ratio than those flying Hurricanes.
After the Battle of Britain, the Spitfire superseded the Hurricane to become the backbone of RAF Fighter Command, and saw action in the European, Mediterranean, Pacific and the South-East Asian theatres. Much loved by its pilots, the Spitfire served in several roles, including interceptor, photo-reconnaissance, fighter-bomber and trainer, and it continued to serve in these roles until the 1950s. The Seafire was a carrier-based adaptation of the Spitfire which served in the Fleet Air Arm from 1942 through to the mid-1950s. Although the original airframe was designed to be powered by a Rolls-Royce Merlin engine producing 1,030 hp (768 kW), it was strong enough and adaptable enough to use increasingly powerful Merlin and, in later marks, Rolls-Royce Griffon engines producing up to 2,340 hp (1,745 kW); as a consequence of this the Spitfire's performance and capabilities improved, sometimes dramatically, over the course of its life.
Mk V (Types 331, 349 & 352)
Spitfire LF.Mk VB, BL479, flown by Group Captain M.W.S Robinson, station commander of RAF Northolt, August 1943. This Spitfire has the wide bladed Rotol propeller, the internal armoured windscreen and "clipped" wings.
Late in 1940, the RAF predicted that the advent of the pressurised Junkers Ju 86P bomber series over Britain would be the start of a new sustained high altitude bombing offensive by the Luftwaffe, in which case development was put in hand for a pressurised version of the Spitfire, with a new version of the Merlin (the Mk VI). It would take some time to develop the new fighter and an emergency stop-gap measure was needed as soon as possible: this was the Mk V.
The basic Mk V was a Mk I with the Merlin 45 series engine. This engine delivered 1,440 hp (1,074 kW) at take-off, and incorporated a new single-speed single-stage supercharger design. Improvements to the carburettor also allowed the Spitfire to use zero gravity manoeuvres without any problems with fuel flow. Several Mk I and Mk II airframes were converted to Mk V standard by Supermarine and started equipping fighter units from early 1941. The majority of the Mk Vs were built at Castle Bromwich.
The VB became the main production version of the Mark Vs. Along with the new Merlin 45 series the B wing was fitted as standard. As production progressed changes were incorporated, some of which became standard on all later Spitfires. Production started with several Mk IBs which were converted to Mk VBs by Supermarine. Starting in early 1941 the round section exhaust stacks were changed to a "fishtail" type, marginally increasing exhaust thrust. Some late production VBs and VCs were fitted with six shorter exhaust stacks per side, similar to those of Spitfire IXs and Seafire IIIs; this was originally stipulated as applying specifically to VB(trop)s. After some initial problems with the original Mk I size oil coolers, a bigger oil cooler was fitted under the port wing; this could be recognised by a deeper housing with a circular entry. From mid-1941 alloy covered ailerons became a universal fitting.
Spitfire VC(trop), fitted with Vokes filters and "disc" wheels, of 417 Squadron RCAF in Tunisia in 1943.
A constant flow of modifications were made as production progressed. A "blown" cockpit hood, manufactured by Malcolm, was introduced in an effort to further increase the pilot's head-room and visibility. Many mid to late production VBs - and all VCs - used the modified, improved windscreen assembly with the integral bullet resistant centre panel and flat side screens introduced with the Mk III. Because the rear frame of this windscreen was taller than that of the earlier model the cockpit hoods were not interchangeable and could be distinguished by the wider rear framing on the hood used with the late-style windscreen.
Different propeller types were fitted, according to where the Spitfire V was built: Supermarine and Westland manufactured VBs and VCs used 10 ft 9 in (3.28 m) diameter, 3 bladed de Havilland constant speed units, with narrow metal blades, while Castle Bromwich manufactured VBs and VCs were fitted with a wide bladed Rotol constant speed propeller of either 10 ft 9 in (3.28 m) diameter, with metal blades, or (on late production Spitfires) 10 ft 3 in (3.12 m) diameter, with broader, "Jablo" (compressed wood) blades. The Rotol spinners were longer and more pointed than the de Havilland leading to a 3.5 in (8.9 cm) increase in overall length. The Rotol propellers allowed a modest speed increase over 20,000 ft (6,100 m) and an increase in the service ceiling. A large number of Spitfire VBs were fitted with "gun heater intensifier" systems on the exhaust stacks. These piped additional heated air into the gun bays. There was a short tubular intake on the front of the first stack and a narrow pipe led into the engine cowling from the rear exhaust.
The VB series were the first Spitfires able to carry a range of specially designed "slipper" drop tanks which were fitted underneath the wing centre-section. Small hooks were fitted, just forward of the inboard flaps: when the tank was released these hooks caught the trailing edge of the tank, swinging it clear of the fuselage.
With the advent of the superb Focke Wulf Fw 190 in August 1941 the Spitfire was for the first time truly outclassed, hastening the development of the "interim" Mk IX. In an effort to counter this threat, especially at lower altitudes, the VB was the first production version of the Spitfire to use "clipped" wingtips as an option, reducing the wingspan to 32 ft 2 in (9.8 m).The clipped wings increased the roll rate and airspeed at lower altitudes. Several different versions of the Merlin 45/50 family were used, including the Merlin 45M which had a smaller "cropped" supercharger impeller and boost increased to +18 lb. This engine produced 1,585 hp (1,182 kW) at 2,750 ft (838 m), increasing the L.F VB's maximum rate of climb to 4720 ft/min (21.6 m/s) at 2,000 ft (610 m).
VB Trop of 40 Squadron SAAF fitted with the "streamlined" version of the Aboukir filter, a broad-bladed, 10 ft 3 in (3.12 m) diameter Rotol propeller, and clipped wings.
The Mk VB(trop) (or type 352) could be identified by the large Vokes air filter fitted under the nose; the reduced speed of the air to the supercharger had a detrimental effect on the performance of the aircraft, reducing the top speed by 8 mph (13 km/h) and the climb rate by 600 ft/min (3.04 m/s), but the decreased performance was considered acceptable. This variant was also fitted with a larger oil tank and desert survival gear behind the pilot's seat. A new "desert" camouflage scheme was applied. Many VB(trop)s were modified by 103 MU (Maintenance Unit-RAF depots in which factory fresh aircraft were brought up to service standards before being delivered to squadrons) at Aboukir, Egypt by replacing the Vokes filter with locally manufactured "Aboukir" filters, which were lighter and more streamlined. Two designs of these filters can be identified in photos: one had a bulky, squared off filter housing while the other was more streamlined. These aircraft were usually fitted with the wide blade Rotol propeller and clipped wings.
Triumph Spitfire Mk I Roadster
The Triumph Spitfire is a small English two-seat sports car, introduced at the London Motor Show in 1962.[3] The vehicle was based on a design produced for Standard-Triumph in 1957 by Italian designer Giovanni Michelotti. The platform for the car was largely based upon the chassis, engine, and running gear of the Triumph Herald saloon, and was manufactured at the Standard-Triumph works at Canley, in Coventry. As was typical for cars of this era, the bodywork was fitted onto a separate structural chassis, but for the Spitfire, which was designed as an open top or convertible sports car from the outset, the ladder chassis was reinforced for additional rigidity by the use of structural components within the bodywork. The Spitfire was provided with a manual hood for weather protection, the design improving to a folding hood for later models. Factory-manufactured hard-tops were also available.
The Triumph Spitfire was originally devised by Standard-Triumph to compete in the small sports car market that had opened up with the introduction of the Austin-Healey Sprite. The Sprite had used the basic drive train of the Austin A30/35 in a light body to make up a budget sports car; Triumph's idea was to use the mechanicals from their small saloon, the Herald, to underpin the new project. Triumph had one advantage, however; where the Austin A30 range was of unitary construction, the Herald featured a separate chassis. It was Triumph's intention to cut that chassis down and clothe it in a sports body, saving the costs of developing a completely new chassis / body unit.
Italian designer Michelotti—who had already penned the Herald—was commissioned for the new project, and came up with a traditional, swooping body. Wind-up windows were provided (in contrast to the Sprite/Midget, which still featured sidescreens, also called curtains, at that time), as well as a single-piece front end which tilted forwards to offer unrivaled access to the engine. At the dawn of the 1960s, however, Standard-Triumph was in deep financial trouble, and unable to put the new car into production; it was not until the company was taken over by the Leyland organization funds became available and the car was launched. Leyland officials, taking stock of their new acquisition, found Michelotti's prototype hiding under a dust sheet in a corner of the factory and rapidly approved it for production.
Spitfire 4 or Mark I (1962-1964)
Overview:
Production1962–1964

Transmission4-speed manual with optional overdrive on top and third from 1963 onwards
Dimensions:
Curb weight1,568 lb (711 kg) (unladen U.K.-spec)
The production car changed little from the prototype, although the full-width rear bumper was dropped in favour of two part-bumpers curving round each corner, with overriders. Mechanicals were basically stock Herald. The engine was an 1,147 cc (1.1 l) 4-cylinder with a pushrod OHV cylinder head and 2 valves per cylinder, mildly tuned for the Spitfire, fed by twin SU carburettors. Also from the Herald came the rack and pinion steering and coil-and-wishbone front suspension up front, and at the rear a single transverse-leaf swing axle arrangement. This ended up being the most controversial part of the car: it was known to "tuck in" and cause violent over steer if pushed too hard, even in the staid Herald. In the sportier Spitfire (and later the 6-cylinder Triumph GT6 and Triumph Vitesse) it led to severe criticism. The body was bolted to a much-modified Herald chassis, the outer rails and the rear outriggers having been removed; little of the original Herald chassis design was left, and the Spitfire used structural outer sills to stiffen its body tub.
The Spitfire was an inexpensive small sports car and as such had very basic trim, including rubber mats and a large plastic steering wheel. These early cars were referred to both as "Triumph Spitfire Mark I" and "Spitfire 4", not to be confused with the later Spitfire Mark IV.
In UK specification the in-line four produced 63 bhp (47 kW) at 5750 rpm, and 67 lb·ft (91 N·m)of torque at 3500 rpm. This gave a top speed of 92 mph (148 km/h), and would achieve 0 to 60 mph (97 km/h) in 17.3 seconds. Average fuel consumption was 31mpg.
For 1964 an overdrive option was added to the 4-speed manual gearbox to give more relaxed cruising. Wire wheels and a hard top were also available.

In UK specification the in-line four produced 63 bhp (47 kW) at 5750 rpm, and 67 lb·ft (91 N·m)of torque at 3500 rpm. This gave a top speed of 92 mph (148 km/h), and would achieve 0 to 60 mph (97 km/h) in 17.3 seconds. Average fuel consumption was 31mpg.
For 1964 an overdrive option was added to the 4-speed manual gearbox to give more relaxed cruising. Wire wheels and a hard top were also available.

The Citroën DS (French pronunciation: [si.tʁɔ.ˈɛn de ɛs]) is a front-engine, front-wheel-drive executive car manufactured and marketed by the French company Citroën from 1955 to 1975 in sedan, wagon/estate and convertible body configurations. Italian sculptor and industrial designer Flaminio Bertoni and the French aeronautical engineer André Lefèbvre styled and engineered the car. Paul Magès developed the hydropneumatic self-levelling suspension.
Noted for its aerodynamic, futuristic body design and innovative technology, the DS set new standards in ride quality, handling, and braking—and was the first production car equipped with disc brakes.
Citroën sold 1,455,746 examples, including 1,330,755 built at the manufacturer's Paris Quai André-Citroën production plant.
The DS came third in the 1999 Car of the Century poll recognizing the world's most influential auto designs and was named the most beautiful car of all time by Classic & Sports Car magazine
MODEL HISTORY
After 18 years of secret development as the successor to the Traction Avant, the DS 19 was introduced on 5 October 1955 at the Paris Motor Show. In the first 15 minutes of the show, 743 orders were taken, and orders for the first day totalled 12,000. During the 10 days of the show, the DS took in 80,000 deposits; a record that has stood for over 60 years.
Contemporary journalists said the DS pushed the envelope in the ride vs. handling compromise possible in a motor vehicle.
To a France still deep in reconstruction after the devastation of World War II, and also building its identity in the post-colonial world, the DS was a symbol of French ingenuity. The DS was distributed to many territories throughout the world.
It also posited the nation's relevance in the Space Age, during the global race for technology of the Cold War. Structuralist philosopher Roland Barthes, in an essay about the car, said that it looked as if it had "fallen from the sky". An American advertisement summarised this selling point: "It takes a special person to drive a special car".
Because they were owned by the technologically aggressive tire manufacturer Michelin, Citroën had designed their cars around the technically superior radial tire since 1948, and the DS was no exception.
The car featured a novel hydropneumatic suspension including an automatic leveling system and variable ground clearance, developed in-house by Paul Magès. This suspension allowed the DS to travel quickly on the poor road surfaces common in France.
In addition, the vehicle had power steering and a semi-automatic transmission (the transmission required no clutch pedal, but gears still had to be shifted by hand), though the shift lever controlled a powered hydraulic shift mechanism in place of a mechanical linkage, and a fibreglass roof which lowered the centre of gravity and so reduced weight transfer. Inboard front brakes (as well as independent suspension) reduced unsprung weight. Different front and rear track widths and tyre sizes reduced the unequal tyre loading, which is well known to promote understeer, typical of front-engined and front-wheel drive cars.
As with all French cars, the DS design was affected by the tax horsepower system, which effectively mandated very small engines. Unlike the Traction Avant predecessor, there was no top-of-range model with a powerful six-cylinder engine. Citroën had planned an air-cooled flat-6 engine for the car, but did not have the funds to put the prototype engine into production.
The DS placed third in the 1999 Car of the Century competition, and fifth on Automobile Magazine's "100 Coolest Cars" listing in 2005. It was also named the most beautiful car of all time by Classic & Sports Car magazine after a poll of 20 world-renowned car designers, including Giorgetto Giugiaro, Ian Callum, Roy Axe, Paul Bracq, and Leonardo Fioravanti.
NAME
Both the DS and its simpler sibling, the ID, used a punning name. "DS" is pronounced in French as "Déesse" (goddess); "ID" is pronounced as "Idée" (idea). An intermediate model was called the DW.
MOTORSPORT
The DS was successful in motorsports like rallying, where sustained speeds on poor surfaces are paramount, and won the Monte Carlo Rally in 1959. In the 1000 Lakes Rally, Pauli Toivonen drove a DS19 to victory in 1962.
In 1966, the DS won the Monte Carlo Rally again, with some controversy as the competitive BMC Mini-Cooper team was disqualified due to rule infractions. Ironically, Mini was involved with DS competition again two years later, when a drunk driver in a Mini in Sydney Australia crashed into the DS that was leading the 1968 London–Sydney Marathon, 98 miles from the finish line. The DS was still competitive in the grueling 1974 London-Sahara-Munich World Cup Rally, where it won over 70 other cars, only 5 of which even completed the entire event.
TECHNICAL INNOVATION - HYDRAULIC SYSTEMS
In conventional cars, hydraulics are only used in brakes and power steering. In the DS they were also used for the suspension, clutch and transmission. The cheaper 1957 ID19 did have manual steering and a simplified power-braking system. An engine driven pump pressurizes the closed system to 2,400 pounds per square inch.
At a time when few passenger vehicles had independent suspension on all wheels, the application of the hydraulic system to the car's suspension system to provide a self-levelling system was an innovative move. This suspension allowed the car to achieve sharp handling combined with very high ride quality, frequently compared to a "magic carpet".
The hydropneumatic suspension used was pioneered the year before, on the rear of another car from Citroën, the top of range Traction Avant 15CV-H.
IMPACT ON CITROEN BRAND DEVELOPMENT
The 1955 DS cemented the Citroën brand name as an automotive innovator, building on the success of the Traction Avant, which had been the world's first mass-produced unitary body front-wheel-drive car in 1934. In fact, the DS caused such a huge sensation that Citroën was apprehensive that future models would not be of the same bold standard. No clean sheet new models were introduced from 1955 to 1970.
The DS was a large, expensive executive car and a downward brand extension was attempted, but without result. Throughout the late 1950s and 1960s Citroën developed many new vehicles for the very large, profitable market segments between the 2CV and the DS, occupied by vehicles like the Peugeot 403, Renault 16 and Ford Cortina, but none made it into production. Either they had uneconomic build costs, or were ordinary "me too" cars, not up to the company's high standard of innovation. As Citroën was owned by Michelin from 1934 to 1974 as a sort of research laboratory, such broad experimentation was possible. Michelin after all was getting a powerful advertisement for the capabilities of the radial tire Michelin had invented, when such experimentation was successful.
New models based on the small, utilitarian 2CV economy car were introduced, notably the 1961 Ami. It was also designed by Flaminio Bertoni and aimed to combine Three-box styling with the chassis of the 2CV. The Ami was very successful in France, but less so on export markets. Many found the styling controversial, and the car noisy and underpowered. The Dyane, was a modernised 2CV with a hatchback, competed with the 2CV inspired Renault 4 Hatchback. All these 2 cylinder models were very small, so there remained a wide market gap to the DS range all through the 1960s.
In 1970, Citroën finally introduced a car to target the mid-range - the Citroën GS, which won the "European car of the Year" for 1971 and sold 2.5 million units. It combined a small 55 horsepower flat-4 air-cooled engine with Hydropneumatic suspension. The intended 106 horsepower Wankel rotary-engined version with more power did not reach full production.
REPLACING THE DS
The DS remained popular and competitive throughout its production run. Its peak production year was 1970. Certain design elements like the somewhat narrow cabin, column-mounted gearstick, and separate fenders began to seem a little old-fashioned in the 1970s.
Citroën invested enormous resources to design and launch an entirely new vehicle in 1970, the SM, which was in effect a thoroughly modernized DS, with similar length, but greater width. The manual gearbox was a modified DS unit. The front disc brakes were the same design. Axles, wheel bearings, steering knuckles, and hydraulic components were either DS parts or modified DS parts.
The SM had a different purpose than replacing the 15-year-old DS design however - it was meant to launch Citroën into a completely new luxury grand touring market segment. Only fitted with a costly, exotic Maserati engine, the SM was faster and much more expensive than the DS. The SM was not designed to be a practical 4-door saloon suitable as a large family car, the key market for vehicles of this type in Europe. Typically, manufacturers would introduce low-volume coupés based on parts shared with an existing saloon, not as unique models, a contemporary example being the Mercedes-Benz SLC-Class.
The SM's high price and limited utility of the 2+2 seating configuration, meant the SM as actually produced could not seize the mantle from the DS.
So, while the design funds invested would allow the DS to be replaced by two cars - a 'modern DS' and the smaller CX, it was left to the CX alone to provide Citroën's large family or executive car in the model range.
The last DS came off the production line on 24 April 1975 - the manufacturer had taken the elementary precaution of building up approximately eight-month's of inventory of the "break" (estate/station wagon) version of the DS, to cover the period till Autumn 1975 when the estate/station wagon version of the CX would be introduced.
DEVELOPMENT
The DS always maintained its size and shape, with easily removable, unstressed body panels, but certain design changes did occur. During the 20-year production life improvements were made on an ongoing basis.
ID 19 submodel to extend brand downwards (1957–69)
The 1955 DS19 was 65% more expensive than the car it replaced, the Citroën Traction Avant. This affected potential sales in a country still recovering economically from World War II, so a cheaper submodel, the Citroën ID, was introduced in 1957.
The ID shared the DS's body but was less powerful and luxurious. Although it shared the engine capacity of the DS engine (at this stage 1,911 cc), the ID provided a maximum power output of only 69 hp compared to the 75 hp claimed for the DS19. Power outputs were further differentiated in 1961 when the DS19 acquired a Weber-32 twin bodied carburettor, and the increasing availability of higher octane fuel enabled the manufacturer to increase the compression ratio from 7.5:1 to 8.5:1. A new DS19 now came with a promised 83 hp of power. The ID19 was also more traditional mechanically: it had no power steering and had conventional transmission and clutch instead of the DS's hydraulically controlled set-up. Initially the basic ID19 was sold on the French market with a price saving of more than 25% against the DS, although the differential was reduced at the end of 1961 when the manufacturer quietly withdrew the entry level ID19 "Normale" from sale. A station wagon variant, the ID Break, was introduced in 1958.
D SPECIAL AND D SUPER (1970–75)
The ID was replaced by the D Spécial and D Super in 1970, but these retained the lower specification position in the range. The D Super was available with the DS21 2175ccm engine and a 5 speed gearbox, and named the D Super 5.
SERIE 2 - NOSE REDESIGN IN 1962
In September 1962, the DS was restyled with a more aerodynamically efficient nose, better ventilation and other improvements. It retained the open two headlamp appearance, but was available with an optional set of driving lights mounted on the front fenders. All models in the range changed nose design at the same time, including the ID and station wagon models.
Series 3 - Nose redesign in 1967 with Directional headlights
In late 1967, for the 1968 model year, the DS and ID was again restyled, by Robert Opron, who also styled the 1970 SM and 1974 CX. This version had a more streamlined headlamp design, giving the car a notably shark-like appearance. This design had four headlights under a smooth glass canopy, and the inner set swivelled with the steering wheel. This allowed the driver to see "around" turns, especially valuable on twisting roads driven at high speed at night.
Behind each glass cover lens, the inboard high-beam headlamp swivels by up to 80° as the driver steers, throwing the beam along the driver's intended path rather than uselessly across the curved road. The outboard low-beam headlamps are self-leveling in response to pitching caused by acceleration and braking.
However, this feature was not allowed in the US at the time (see World Forum for Harmonization of Vehicle Regulations), so a version with four exposed headlights that did not swivel was made for the US market.
This 'turning headlight' feature was new to the market - it had only been seen before on the very rare three headlight 1935 Tatra 77A. The Tucker, which never was mass-produced, had a central headlight that turned with the steering. 45 years later, it is now a commonly available feature, even in the United States.
NEW GREEN HYDRAULIC FLUID
The original hydropneumatic system used a vegetable oil liquide hydraulique végétal (LHV), similar to that used in other cars at the time, but later switched to a synthetic fluid liquide hydraulique synthétique (LHS). Both of these had the disadvantage that they are hygroscopic, as is the case with most brake fluids. Disuse allows water to enter the hydraulic components causing deterioration and expensive maintenance work. The difficulty with hygroscopic hydraulic fluid was exacerbated in the DS/ID due to the extreme rise and fall in the fluid level in the reservoir, which went from nearly full to nearly empty when the suspension extended to maximum height and the six accumulators in the system filled with fluid. With every "inhalation" of fresh moisture- (and dust-) laden air, the fluid absorbed more water.
For the 1967 model year, Citroën introduced a new mineral oil-based fluid LHM (Liquide Hydraulique Minéral). This fluid was much less harsh on the system. LHM remained in use within Citroën until the Xantia was discontinued in 2001.
LHM required completely different materials for the seals. Using either fluid in the incorrect system would completely destroy the hydraulic seals very quickly. To help avoid this problem, Citroën added a bright green dye to the LHM fluid and also painted all hydraulic elements bright green. The former LHS parts were painted black.
All models, including the station wagon and ID, were upgraded at the same time. The hydraulic fluid changed to the technically superior LHM in all markets except the US and Canada, where the change did not take place until January 1969, due to local regulations.
INTERNATIONAL SALES AND PRODUCTION
The DS was primarily manufactured at the Quai André-Citroën in the Javel neighborhood of Paris, with other manufacturing facilities in the United Kingdom, South Africa, the former Yugoslavia (mostly Break Ambulances), and Australia.
Australia constructed their own D variant in the 1960s at Heidelberg, Victoria, identified as the ID 19 "Parisienne." Australian market cars were fitted with options as standard equipment such as the "DSpecial DeLuxe" that were not available on domestic European models.
Until 1965, cars were assembled at the manufacturer's Slough premises, to the west of London, using a combination of French made knock down kits and locally sourced components, some of them machined on site. A French electrical system superseded the British one on the Slough cars in 1962, giving rise to a switch to "continental style" negative earthing. After 1965 cars for the British market were imported fully assembled from the company's French plant. The British-built cars are distinguished by their leather seats, wooden (early ID19 models) one piece plastic (early DS19 models) dashboards, chromed number plate mount let into the front bumper, and (on pre-1962 cars) Lucas-made electrics. These were all right hand drive cars.
The DS was built and sold in South Africa from 1959 to 1975.
The DS was sold in Japan, but the models were built in France and left hand drive.
DS IN NORTH AMERICA
The DS was sold in North America from 1956 to 1972. Despite its popularity in Europe, it didn't sell well in the United States, and little better in Canada. While promoted as a luxury car, it did not have the basic features that American buyers expected to find on such a vehicle, such as an automatic transmission, air conditioning, power windows, or a powerful engine. The DS was designed specifically to address the French market, with punitive tax horsepower taxation of large engines, as well as very poor roads – it's no great mystery that it was a fish out of water when those constraints were removed.
Jay Leno described the sporadic supply of spare parts as a problem for 1970s era customers, based on his early experiences working at a Citroën dealer in Boston.
The DS was expensive, with a 115 hp (86 kW) vehicle costing $4,170 in 1969, when the price was $4,500 for a 360 hp (268 kW) Buick Electra 225 4 door sedan. For all years, 38,000 units were sold.
US regulations at the time also banned one of the car's more advanced features: its composite headlamps with aerodynamic covered lenses. Based on legislation that dated from 1940, all automobiles sold in the U.S. were required to have round, sealed beam headlamps that produced a meager 75,000 candlepower. The powerful quartz iodine swiveling headlamps designed for the 1968 model DS represented so many performance improvements at once that they were far beyond what the regulations could allow.[50] Even the aerodynamic headlight covers were illegal – as seen on the 1968 Jaguar E-Type. It took the lobbying muscle of Ford to point out that the government was requiring two contradictory things – safety, by ensuring that all headlights were best-of-breed circa 1940, and fuel economy through the CAFE standard – by definition, cars with poor aerodynamics are sacrificing fuel economy. Composite bulb lamps and aerodynamic covered headlights were not permitted until 1983.
The European lamps were legal in Canada, including the directional headlamps.
The hydraulic fluid change in 1967 was another brain teaser for U.S. automotive regulators at the Department of Transportation. NHTSA follows the precautionary principle, also used by the Food and Drug Administration, where new innovations are prohibited until their developers can prove them to the regulators; this stifles the experimentation that automakers need to advance their products. NHTSA had already approved a brake fluid they considered safe – DOT 3 brake fluid, which is red and hygroscopic to promote internal rust. This completely different fluid, used in aircraft applications – the technically superior green LHM (Liquide Hydraulique Mineral) – took NHTSA two years to analyze for automotive use. Approval finally came in January 1969, so half the U.S. cars of the 1969 model year use red fluid and half use green fluid.
DESIGN VARIATIONS
PALLAS
In 1965 a luxury upgrade, the DS Pallas (after Greek goddess Pallas), was introduced. This included comfort features such as better noise insulation, a more luxurious (and optional leather) upholstery and external trim embellishments. From 1966 the Pallas model received a driver's seat with height adjustment.
STATION WAGON, FAMILIALE AND AMBULANCE
A station wagon version was introduced in 1958. It was known by various names in different markets (Break in France, Safari and Estate in the UK, Wagon in the US, and Citroën Australia used the terms Safari and Station-Wagon). It had a steel roof to support the standard roof rack. 'Familiales' had a rear seat mounted further back in the cabin, with three folding seats between the front and rear squabs. The standard Break had two side-facing seats in the main load area at the back.
The Ambulance configuration was similar to that of the Break, but with a 60/30 split in the rear folding seat to accommodate a stretcher. A 'Commerciale' version was also available for a time.
The Safari saw use as a camera car, notably by the BBC. The hydropneumatic suspension produces an unusually steady platform for filming while driving.
CONVERTIBLE
Rarest and most collectable of all DS variants, a convertible was offered from 1958 until 1973. The Cabriolet d'Usine (factory convertible) were built by French carrossier Henri Chapron, for the Citroën dealer network. It was an expensive car, so only 1,365 were sold. These DS convertibles used a special frame which was reinforced on the sidemembers and rear suspension swingarm bearing box, similar to, but not identical to the Break (Station Wagon) frame.
CHAPRON VARIATIONS
In addition, Chapron also produced a few coupés, non-works convertibles and special sedans (including the "Prestige", same wheelbase but with a central divider, and the "Lorraine" notchback).
BOSSAERT COUPE
Between 1959 and 1964, Hector Bossaert produced a coupé on a DS chassis shortened by 470 mm. While the front end remained unchanged, the rear end featured notchback styling.
THE REACTOR
In 1965, noted American auto customizer Gene Winfield created The Reactor, a Citroën DS chassis, with a turbocharged 180 hp (130 kW) flat-six engine from the Corvair driving the front wheels. Since the DS already had the engine behind the front wheels, the longer engine meant only one row of seats. This was draped in a streamlined, low slung, aluminum body.
The Reactor was seen in American Television programs of the era, such as Star Trek: The Original Series episode 2.25 ("Bread and Circuses)," Batman episodes 110 ("Funny Feline Felonies") and 111 (driven by Catwoman Eartha Kitt), and Bewitched, which devoted its episode 3.19 ("Super Car") to The Reactor.
MICHELIN PLR
The Michelin PLR is a mobile tire evaluation machine, based on the DS Break, built in 1972, later used for promotion.
Technical details
SUSPENSION
In a hydropneumatic suspension system, each wheel is connected, not to a spring, but to a hydraulic suspension unit consisting of a hydraulic accumulator sphere of about 12 cm in diameter containing pressurised nitrogen, a cylinder containing hydraulic fluid screwed to the suspension sphere, a piston inside the cylinder connected by levers to the suspension itself, and a damper valve between the piston and the sphere. A membrane in the sphere prevented the nitrogen from escaping. The motion of the wheels translated to a motion of the piston, which acted on the oil in the nitrogen cushion and provided the spring effect. The damper valve took place of the shock absorber in conventional suspensions. The hydraulic cylinder was fed with hydraulic fluid from the main pressure reservoir via a height corrector, a valve controlled by the mid-position of the anti-roll bar connected to the axle. If the suspension was too low, the height corrector introduced high-pressure fluid; if it was too high, it released fluid back to the fluid reservoir. In this manner, a constant ride height was maintained. A control in the cabin allowed the driver to select one of five heights: normal riding height, two slightly higher riding heights for poor terrain, and two extreme positions for changing wheels. (The correct term, oleopneumatic (oil-air), has never gained widespread use. Hydropneumatic (water-air) continues to be preferred overwhelmingly.)
The DS did not have a jack for lifting the car off the ground. Instead, the hydraulic system enabled wheel changes with the aid of a simple adjustable stand. To change a flat tyre, one would adjust the suspension to its topmost setting, insert the stand into a special peg near the flat tyre, then readjust the suspension to its lowermost setting. The flat tyre would then retract upwards and hover above ground, ready to be changed. This system, used on the SM also, was superseded on the CX by a screw jack that, after the suspension was raised to the high position, lifted the tire clear of the ground. The DS system, while impressive to use, sometimes dropped the car quite suddenly, especially if the stand was not placed precisely or the ground was soft or unlevel.
SOURCE AND RESERVE OF PRESSURE
The central part of the hydraulic system was the high pressure pump, which maintained a pressure of between 130 and 150 bar in two accumulators. These accumulators were very similar in construction to the suspension spheres. One was dedicated to the front brakes, and the other ran the other hydraulic systems. (On the simpler ID models, the front brakes operated from the main accumulator.) Thus in case of a hydraulic failure, the first indication would be that the steering became heavy, followed by the gearbox not working; only later would the brakes fail.
Two different hydraulic pumps were used. The DS used a seven-cylinder axial piston pump driven off two belts and delivering 175 bar (2,540 psi) of pressure. The ID19, with its simpler hydraulic system, had a single-cylinder pump driven by an eccentric on the camshaft.
GEARBOX AND CLUTCH
HYDRAULIQUE OR CITROMATIC
The DS was initially offered only with the "hydraulique" four-speed semi-automatic (bvh—"boîte de vitesses hydraulique") gearbox.
This was a four-speed gearbox and clutch, operated by a hydraulic controller. To change gears, the driver flicked a lever behind the steering wheel to the next position and eased-up on the accelerator pedal. The hydraulic controller disengaged the clutch, engaged the nominated gear, and re-engaged the clutch. The speed of engagement of the clutch was controlled by a centrifugal regulator sensing engine rpm and driven off the camshaft by a belt, the position of the butterfly valve in the carburettor (i.e., the position of the accelerator), and the brake circuit. When the brake was pressed, the engine idle speed dropped to an rpm below the clutch engagement speed, thus preventing friction while stopped in gear at traffic lights. When the brake was released, the idle speed increased to the clutch dragging speed. The car would then creep forward much like automatic transmission cars. This drop in idle throttle position also caused the car to have more engine drag when the brakes were applied even before the car slowed to the idle speed in gear, preventing the engine from pulling against the brakes. In the event of loss of hydraulic pressure (following loss of system fluid), the clutch would disengage, to prevent driving, while brake pressure reserves would allow safe braking to standstill.
MANUAL - FOUR SPEED AND FIVE-SPEED
The later and simpler ID19 had the same gearbox and clutch, manually operated. This configuration was offered as a cheaper option for the DS in 1963. The mechanical aspects of the gearbox and clutch were completely conventional and the same elements were used in the ID 19. In September 1970, Citroën introduced a five-speed manual gearbox, in addition to the original four-speed unit.
FULLY AUTOMATIC
In September 1971 Citroën introduced a 3-speed fully automatic Borg-Warner 35 transmission gearbox, on the DS 21 and later DS 23 models. It is ironic that the fully automatic transmission DS was never sold in the US market, where this type of transmission had gained market share so quickly that it became the majority of the market by this time. Many automatic DSs, fuel-injected DS 23 sedans with air conditioning, were sold in Australia.
ENGINES
The DS was originally designed around an air-cooled flat-six based on the design of the 2-cylinder engine of the 2CV, similar to the motor in the Porsche 911. Technical and monetary problems forced this idea to be scrapped.
Thus, for such a modern car, the engine of the original DS 19 was also old-fashioned. It was derived from the engine of the 11CV Traction Avant (models 11B and 11C). It was an OHV four-cylinder engine with three main bearings and wet liners, and a bore of 78 mm and a stroke of 100 mm, giving a volumetric displacement of 1911 cc. The cylinder head had been reworked; the 11C had a reverse-flow cast iron cylinder head and generated 60 hp (45 kW) at 3800 rpm; by contrast, the DS 19 had an aluminium cross-flow head with hemispherical combustion chambers and generated 75 hp (56 kW) at 4500 rpm.
Like the Traction Avant, the DS had the gearbox mounted in front of the engine, with the differential in between. Thus some consider the DS to be a mid engine front-wheel drive car.
The DS and ID powerplants evolved throughout its 20-year production life. The car was underpowered and faced constant mechanical changes to boost the performance of the four-cylinder engine. The initial 1911 cc three main bearing engine (carried forward from the Traction Avant) of the DS 19 was replaced in 1965 with the 1985 cc five-bearing wet-cylinder motor, becoming the DS 19a (called DS 20 from September 1969).
The DS 21 was also introduced for model year 1965. This was a 2175 cc, five main bearing engine; power was 109 hp This engine received a substantial increase in power with the introduction of Bosch electronic fuel injection for 1970, making the DS one of the first mass-market cars to use electronic fuel injection. Power of the carbureted version also increased slightly at the same time, owing to the employment of larger inlet valves.
Lastly, 1973 saw the introduction of the 2347 cc engine of the DS 23 in both carbureted and fuel-injected forms. The DS 23 with electronic fuel injection was the most powerful production model, producing 141 hp (105 kW).
IDs and their variants went through a similar evolution, generally lagging the DS by about one year. ID saloon models never received the DS 23 engine or fuel injection, although the Break/Familiale versions received the carburetted version of the DS 23 engine when it was introduced, supplemented the DS20 Break/Familiale.
The top of the range ID model, The DSuper5 (DP) gained the DS21 engine (the only model that this engine was retained in) for the 1973 model year and it was mated to a five-speed gearbox. This should not be confused with the 1985 cc DSuper fitted with an optional "low ratio" five-speed gearbox, or with the previous DS21M (DJ) five-speed.
IN POPULAR CULTURE
President Charles de Gaulle survived an assassination attempt at Le Petit-Clamart near Paris on August 22, 1962, planned by Algerian War veteran Jean-Marie Bastien-Thiry. The plan was to ambush the motorcade with machine guns, disable the vehicles, and then close in for the kill. De Gaulle praised the unusual abilities of his unarmoured DS with saving his life – the car was peppered with bullets, and the shots had punctured the tyres, but the car could still escape at full speed. This event was accurately recreated in the 1973 film The Day of the Jackal.
Beyond de Gaulle and the French aristocracy, the roomy DS also appealed to French taxi drivers.
Outside France, the car drew an eclectic customer mix, such as Cosmonaut Yuri Gagarin, Pope John XXIII, painter Marc Chagall, and actors Ken Berry, Jeff Bridges, and Rosamund Pike.
The DS appeared in several episodes of contemporary television series Mission: Impossible, including substantial appearances in 'The Slave' (ep. 2.06) and 'Robot' (ep. 4.09).
An ode to Jane Child's DS21 appears on her 1989 self-titled album.
In 1989, the film Back to the Future Part II featured a modified Citroen DS as a flying taxicab, when the main characters travel 30 years into the future (2015). Scarface (1983 film) with Al Pacino and the 2009 television series The Mentalist both feature the DS in key roles. According to Internet Movie Cars Database, the DS/ID has made over 2,000 film and television appearances so far.
Two films focus on the DS, including The Goddess of 1967 about a Japanese man purchasing a DS (goddess or déesse in French) in Australia, and 1995's Icelandic-Japanese road movie Cold Fever.
LEGACY
Citroën DS values have been rising – a 1973 DS 23 Injection Electronique "Decapotable" (Chapron Convertible) sold for EUR €176,250 (USD $209,738) at Christie's Rétromobile in February 2006. and a similar car sold by Bonhams in February 2009 brought EUR €343,497 (USD $440,436). On 18 September 2009 a 1966 DS21 Decapotable Usine was sold by Bonhams for a hammer price of UK£131,300. Bonhams sold another DS21 Decapotable (1973) on 23 January 2010 for EUR €189,000.
The DS's beloved place in French society was demonstrated in Paris on 9 October 2005 with a celebration of the 50th anniversary of its launch. 1,600 DS cars drove in procession past the Arc de Triomphe.
From 2005 to 2008, a young Frenchman named Manuel Boileau travelled around the world in a 1971 DS ambulance. It was an 80,000 kilometer journey across 38 countries called Lunaya World Tour. While traveling through Laos, he located the forlorn 1974 DS Prestige belonging to Sisavang Vatthana, the last King of the Kingdom of Laos, which is now preserved and restored by specialists in Bangkok.
In 2009, Groupe PSA created a new brand - DS Automobiles, intended as high quality, high specification variations on existing models, with differing mechanics and bodywork. This brand ranges across four models, the DS3, DS4, DS5, and the China-only SUV DS 6. The DS3, launched in March 2010, is based on Citroen's new C3, but is more customisable and unique, bearing some resemblance to the original DS, with its "Shark Fin" side pillar. These have created their own niches, with the DS4 being a mix of a crossover and a coupe and the DS5 mixing a coupe and an estate. Many feature hybrid-diesel engines to maximise efficiency.

Evnet/ Location: 2024 RIAT/ RAF Fairford
Comment: The demonstration of the Qatari Boeing two F-15QA consisted of two different configurations: one with a 'clean' fit, the second with a simulated full weapons load to demonstrate how little the aircraft's aerodynamic performance is affected by the additional weight/drag. The aircraft themselves were en route to Qatar on their delivery flights from the US, with the demos at RIAT provided by Boeing test-pilots.
Ugly? Yes, very ugly. But, it gets the job done. In this configuration, the flash fires in a direction perpendicular to the plane of the lens. The inside of this $1 plastic container is coated with aluminum tape to make it extremely reflective. The flash thus bounces off the far side of the container and reflects out through the sheet of white paper from all interior points at once. This design eliminates all hot spots and produces essentially uniform brightness from all points. It allows you to shoot at 5:1 without the problem of having the underside of the subject be too dark--a problem I have found with a round, beauty dish style of diffuser.
To make the channel at the bottom, I cut out a section of the original container and then made a new curved piece to fill in the gap. You want this diffuser to be completely sealed, because using bounce flash eats up the batteries fast, and any escaping light makes that problem worse. I took a piece of stiff manila folder and reinforced it with aluminum tape on both sides to make it stiffer and reflective.
I have only used this reflector for a handful of shots, but I have found it to be quite effective (certainly more so than others I have made, at least). My main goal was to get adequate light under the subject at 4:1 or greater magnification without buying a MT-24EX flash. This diffuser still doesn't do as well as the MT-24EX with a concave diffuser system, but it's much cheaper when you already have a 580EXII or 430EXII in your kit.
Update: I no longer use this design. I have purchased a MT-24EX and use a dual-dome diffuser. The light quality is similar to this setup, but the equipment is much lighter and faster to adjust.
In this 4th post for my "new" Hasselblad 500C/M camera, I have shown the main components of the configuration pictured in the 3rd post separated out from one another. This helps to make the point that this is a "system" camera - i.e., that the camera has a modular architecture that permits the photographer to readily swap out many of the major components for alternatives.
The Hasselblad 500C/M medium format film camera that I got as a Christmas present had a fairly standard configuration - 80mm lens, A12 film back, and waist-level viewfinder. Knowing that there are different options for these components, I turned to the internet to see what was on offer. It came as no surprise to read that there were a range of different lenses for the camera - this is a feature that is available for many cameras. It is a little more unusual that there are quite a few different viewfinders options available. But what really stood out was that the camera back could be swapped out, even in the middle of a roll of film. Having inserted a sheet of metal known as a "dark slide" that stops light from reaching the film, the back can be separated from the rest of the camera. It can then be replaced with a different back, perhaps one with a different film type in it - e.g., a color film versus B&W, a film with a different ISO, etc.
And then the biggest surprise of all - that the film back can be replaced with a digital back. These backs have a CPU to control the unit, a light sensitive digital sensor array, a compact flash card storage system, and a screen for viewing the controls and the pictures that are taken. Based on sensor resolution, there are 3 different lines of digital backs for the Hasselblad 500 (V) series of cameras - 16MP, 39MP and 50MP. Shown here is a CFV16 II second generation 16MP digital back. Having bought this digital back, I now have a camera that can shoot with both film and digital formats. The latter is proving to be very useful as I begin to learn how to use the camera. The immediate feedback obtained with a digital system is speeding up the learning process considerably!

The Supermarine Spitfire is a British single-seat fighter aircraft that was used by the Royal Air Force and many other Allied countries during and after the Second World War. The Spitfire was built in many variants, using several wing configurations, and was produced in greater numbers than any other British aircraft. It was also the only British fighter to be in continuous production throughout the war. The Spitfire continues to be a popular aircraft, with approximately 55 Spitfires being airworthy, while many more are static exhibits in aviation museums all over the world.
The Spitfire was designed as a short-range, high-performance interceptor aircraft by R. J. Mitchell, chief designer at Supermarine Aviation Works (which operated as a subsidiary of Vickers-Armstrong from 1928). In accordance with its role as an interceptor, Mitchell designed the Spitfire's distinctive elliptical wing to have the thinnest possible cross-section; this thin wing enabled the Spitfire to have a higher top speed than several contemporary fighters, including the Hawker Hurricane. Mitchell continued to refine the design until his death from cancer in 1937, whereupon his colleague Joseph Smith took over as chief designer, overseeing the development of the Spitfire through its multitude of variants.
During the Battle of Britain (July–October 1940), the Spitfire was perceived by the public to be the RAF fighter, though the more numerous Hawker Hurricane shouldered a greater proportion of the burden against the Luftwaffe. However, because of its higher performance, Spitfire units had a lower attrition rate and a higher victory-to-loss ratio than those flying Hurricanes.
After the Battle of Britain, the Spitfire superseded the Hurricane to become the backbone of RAF Fighter Command, and saw action in the European, Mediterranean, Pacific and the South-East Asian theatres. Much loved by its pilots, the Spitfire served in several roles, including interceptor, photo-reconnaissance, fighter-bomber and trainer, and it continued to serve in these roles until the 1950s. The Seafire was a carrier-based adaptation of the Spitfire which served in the Fleet Air Arm from 1942 through to the mid-1950s. Although the original airframe was designed to be powered by a Rolls-Royce Merlin engine producing 1,030 hp (768 kW), it was strong enough and adaptable enough to use increasingly powerful Merlin and, in later marks, Rolls-Royce Griffon engines producing up to 2,340 hp (1,745 kW); as a consequence of this the Spitfire's performance and capabilities improved, sometimes dramatically, over the course of its life.
Mk V (Types 331, 349 & 352)
Spitfire LF.Mk VB, BL479, flown by Group Captain M.W.S Robinson, station commander of RAF Northolt, August 1943. This Spitfire has the wide bladed Rotol propeller, the internal armoured windscreen and "clipped" wings.
Late in 1940, the RAF predicted that the advent of the pressurised Junkers Ju 86P bomber series over Britain would be the start of a new sustained high altitude bombing offensive by the Luftwaffe, in which case development was put in hand for a pressurised version of the Spitfire, with a new version of the Merlin (the Mk VI). It would take some time to develop the new fighter and an emergency stop-gap measure was needed as soon as possible: this was the Mk V.
The basic Mk V was a Mk I with the Merlin 45 series engine. This engine delivered 1,440 hp (1,074 kW) at take-off, and incorporated a new single-speed single-stage supercharger design. Improvements to the carburettor also allowed the Spitfire to use zero gravity manoeuvres without any problems with fuel flow. Several Mk I and Mk II airframes were converted to Mk V standard by Supermarine and started equipping fighter units from early 1941. The majority of the Mk Vs were built at Castle Bromwich.
The VB became the main production version of the Mark Vs. Along with the new Merlin 45 series the B wing was fitted as standard. As production progressed changes were incorporated, some of which became standard on all later Spitfires. Production started with several Mk IBs which were converted to Mk VBs by Supermarine. Starting in early 1941 the round section exhaust stacks were changed to a "fishtail" type, marginally increasing exhaust thrust. Some late production VBs and VCs were fitted with six shorter exhaust stacks per side, similar to those of Spitfire IXs and Seafire IIIs; this was originally stipulated as applying specifically to VB(trop)s. After some initial problems with the original Mk I size oil coolers, a bigger oil cooler was fitted under the port wing; this could be recognised by a deeper housing with a circular entry. From mid-1941 alloy covered ailerons became a universal fitting.
Spitfire VC(trop), fitted with Vokes filters and "disc" wheels, of 417 Squadron RCAF in Tunisia in 1943.
A constant flow of modifications were made as production progressed. A "blown" cockpit hood, manufactured by Malcolm, was introduced in an effort to further increase the pilot's head-room and visibility. Many mid to late production VBs - and all VCs - used the modified, improved windscreen assembly with the integral bullet resistant centre panel and flat side screens introduced with the Mk III. Because the rear frame of this windscreen was taller than that of the earlier model the cockpit hoods were not interchangeable and could be distinguished by the wider rear framing on the hood used with the late-style windscreen.
Different propeller types were fitted, according to where the Spitfire V was built: Supermarine and Westland manufactured VBs and VCs used 10 ft 9 in (3.28 m) diameter, 3 bladed de Havilland constant speed units, with narrow metal blades, while Castle Bromwich manufactured VBs and VCs were fitted with a wide bladed Rotol constant speed propeller of either 10 ft 9 in (3.28 m) diameter, with metal blades, or (on late production Spitfires) 10 ft 3 in (3.12 m) diameter, with broader, "Jablo" (compressed wood) blades. The Rotol spinners were longer and more pointed than the de Havilland leading to a 3.5 in (8.9 cm) increase in overall length. The Rotol propellers allowed a modest speed increase over 20,000 ft (6,100 m) and an increase in the service ceiling. A large number of Spitfire VBs were fitted with "gun heater intensifier" systems on the exhaust stacks. These piped additional heated air into the gun bays. There was a short tubular intake on the front of the first stack and a narrow pipe led into the engine cowling from the rear exhaust.
The VB series were the first Spitfires able to carry a range of specially designed "slipper" drop tanks which were fitted underneath the wing centre-section. Small hooks were fitted, just forward of the inboard flaps: when the tank was released these hooks caught the trailing edge of the tank, swinging it clear of the fuselage.
With the advent of the superb Focke Wulf Fw 190 in August 1941 the Spitfire was for the first time truly outclassed, hastening the development of the "interim" Mk IX. In an effort to counter this threat, especially at lower altitudes, the VB was the first production version of the Spitfire to use "clipped" wingtips as an option, reducing the wingspan to 32 ft 2 in (9.8 m).The clipped wings increased the roll rate and airspeed at lower altitudes. Several different versions of the Merlin 45/50 family were used, including the Merlin 45M which had a smaller "cropped" supercharger impeller and boost increased to +18 lb. This engine produced 1,585 hp (1,182 kW) at 2,750 ft (838 m), increasing the L.F VB's maximum rate of climb to 4720 ft/min (21.6 m/s) at 2,000 ft (610 m).
VB Trop of 40 Squadron SAAF fitted with the "streamlined" version of the Aboukir filter, a broad-bladed, 10 ft 3 in (3.12 m) diameter Rotol propeller, and clipped wings.
The Mk VB(trop) (or type 352) could be identified by the large Vokes air filter fitted under the nose; the reduced speed of the air to the supercharger had a detrimental effect on the performance of the aircraft, reducing the top speed by 8 mph (13 km/h) and the climb rate by 600 ft/min (3.04 m/s), but the decreased performance was considered acceptable. This variant was also fitted with a larger oil tank and desert survival gear behind the pilot's seat. A new "desert" camouflage scheme was applied. Many VB(trop)s were modified by 103 MU (Maintenance Unit-RAF depots in which factory fresh aircraft were brought up to service standards before being delivered to squadrons) at Aboukir, Egypt by replacing the Vokes filter with locally manufactured "Aboukir" filters, which were lighter and more streamlined. Two designs of these filters can be identified in photos: one had a bulky, squared off filter housing while the other was more streamlined. These aircraft were usually fitted with the wide blade Rotol propeller and clipped wings.
Triumph Spitfire Mk I Roadster
The Triumph Spitfire is a small English two-seat sports car, introduced at the London Motor Show in 1962.[3] The vehicle was based on a design produced for Standard-Triumph in 1957 by Italian designer Giovanni Michelotti. The platform for the car was largely based upon the chassis, engine, and running gear of the Triumph Herald saloon, and was manufactured at the Standard-Triumph works at Canley, in Coventry. As was typical for cars of this era, the bodywork was fitted onto a separate structural chassis, but for the Spitfire, which was designed as an open top or convertible sports car from the outset, the ladder chassis was reinforced for additional rigidity by the use of structural components within the bodywork. The Spitfire was provided with a manual hood for weather protection, the design improving to a folding hood for later models. Factory-manufactured hard-tops were also available.
The Triumph Spitfire was originally devised by Standard-Triumph to compete in the small sports car market that had opened up with the introduction of the Austin-Healey Sprite. The Sprite had used the basic drive train of the Austin A30/35 in a light body to make up a budget sports car; Triumph's idea was to use the mechanicals from their small saloon, the Herald, to underpin the new project. Triumph had one advantage, however; where the Austin A30 range was of unitary construction, the Herald featured a separate chassis. It was Triumph's intention to cut that chassis down and clothe it in a sports body, saving the costs of developing a completely new chassis / body unit.
Italian designer Michelotti—who had already penned the Herald—was commissioned for the new project, and came up with a traditional, swooping body. Wind-up windows were provided (in contrast to the Sprite/Midget, which still featured sidescreens, also called curtains, at that time), as well as a single-piece front end which tilted forwards to offer unrivaled access to the engine. At the dawn of the 1960s, however, Standard-Triumph was in deep financial trouble, and unable to put the new car into production; it was not until the company was taken over by the Leyland organization funds became available and the car was launched. Leyland officials, taking stock of their new acquisition, found Michelotti's prototype hiding under a dust sheet in a corner of the factory and rapidly approved it for production.
Spitfire 4 or Mark I (1962-1964)
Overview:
Production1962–1964

Transmission4-speed manual with optional overdrive on top and third from 1963 onwards
Dimensions:
Curb weight1,568 lb (711 kg) (unladen U.K.-spec)
The production car changed little from the prototype, although the full-width rear bumper was dropped in favour of two part-bumpers curving round each corner, with overriders. Mechanicals were basically stock Herald. The engine was an 1,147 cc (1.1 l) 4-cylinder with a pushrod OHV cylinder head and 2 valves per cylinder, mildly tuned for the Spitfire, fed by twin SU carburettors. Also from the Herald came the rack and pinion steering and coil-and-wishbone front suspension up front, and at the rear a single transverse-leaf swing axle arrangement. This ended up being the most controversial part of the car: it was known to "tuck in" and cause violent over steer if pushed too hard, even in the staid Herald. In the sportier Spitfire (and later the 6-cylinder Triumph GT6 and Triumph Vitesse) it led to severe criticism. The body was bolted to a much-modified Herald chassis, the outer rails and the rear outriggers having been removed; little of the original Herald chassis design was left, and the Spitfire used structural outer sills to stiffen its body tub.
The Spitfire was an inexpensive small sports car and as such had very basic trim, including rubber mats and a large plastic steering wheel. These early cars were referred to both as "Triumph Spitfire Mark I" and "Spitfire 4", not to be confused with the later Spitfire Mark IV.
In UK specification the in-line four produced 63 bhp (47 kW) at 5750 rpm, and 67 lb·ft (91 N·m)of torque at 3500 rpm. This gave a top speed of 92 mph (148 km/h), and would achieve 0 to 60 mph (97 km/h) in 17.3 seconds. Average fuel consumption was 31mpg.
For 1964 an overdrive option was added to the 4-speed manual gearbox to give more relaxed cruising. Wire wheels and a hard top were also available.

The Volkswagen Type 2, officially known as the Transporter or informally as Bus (US) or Camper (UK), was a panel van introduced in 1950 by German automaker Volkswagen as its second car model – following and initially deriving from Volkswagen's first model, the Type 1 (Beetle), it was given the factory designation Type 2.
As one of the forerunners of the modern cargo and passenger vans, the Type 2 gave rise to competitors in the United States and Europe, including the Ford Econoline, the Dodge A100, and the Corvair 95 Corvan, the latter adopting the Type 2's rear-engine configuration. European competition included the Renault Estafette and the Ford Transit. As of January 2010, updated versions of the Type 2 remain in production in international markets— as a passenger van, as a cargo van, and as a pickup truck.
Like the Beetle, the van has received numerous nicknames worldwide, including the "microbus", "minibus", "kombi" and, due to its popularity during the counterculture movement of the 1960s, "hippie van".
The concept for the Type 2 is credited to Dutch Volkswagen importer Ben Pon. (It has similarities in concept to the 1920s Rumpler Tropfenwagen and 1930s Dymaxion car by Buckminster Fuller, neither of which reached production.) Pon visited Wolfsburg in 1946, intending to purchase Type 1s for import to Holland, where he saw an improvised parts-mover and realized something better was possible using the stock Type 1 pan. He first sketched the van in a doodle dated April 23, 1947, proposing a payload of 690 kg (1,500 lb) and placing the driver at the very front. Production would have to wait, however, as the factory was at capacity producing the Type 1.
When capacity freed up a prototype known internally as the Type 29 was produced in a short three months. The stock Type 1 pan proved to be too weak so the prototype used a ladder chassis with unit body construction. Coincidentally the wheelbase was the same as the Type 1's. Engineers reused the reduction gear from the Type 81, enabling the 1.5 ton van to use a 25 hp (19 kW) flat four engine.
Although the aerodynamics of the first prototypes were poor (with an initial drag coefficient of 0.75), engineers used the wind tunnel at the Technical University of Braunschweig to optimize the design. Simple changes such as splitting the windshield and roofline into a "vee" helped the production Type 2 achieve a drag coefficient of 0.44, exceeding the Type 1's 0.48. Volkswagen's new chief executive officer Heinz Nordhoff (appointed 1 January 1948) approved the van for production on 19 May 1949 and the first production model, now designated Type 2, rolled off the assembly line to debut 12 November. Only two models were offered: the Kombi (with two side windows and middle and rear seats that were easily removable by one person), and the Commercial. The Microbus was added in May 1950, joined by the Deluxe Microbus in June 1951. In all 9,541 Type 2s were produced in their first year of production.
An ambulance model was added in December 1951 which repositioned the fuel tank in front of the transaxle, put the spare tire behind the front seat, and added a "tailgate"-style rear door. These features became standard on the Type 2 from 1955 to 1967. 11,805 Type 2s were built in the 1951 model year. These were joined by a single-cab pickup in August 1952, and it changed the least of the Type 2s until all were heavily modified in 1968.
Unlike other rear engine Volkswagens, which evolved constantly over time but never saw the introduction of all-new models, the Transporter not only evolved, but was completely revised periodically with variations retrospectively referred to as versions "T1" to "T5" (a nomenclature only invented after the introduction of the front-drive T4 which repaced the T25) However only generations T1 to T3 (or T25 as it is still called in Ireland and Great Britain) can be seen as directly related to the Beetle (see below for details).
The Type 2, along with the 1947 Citroën H Van, are among the first 'forward control' vans in which the driver was placed above the front roadwheels. They started a trend in Europe, where the 1952 GM Bedford CA, 1959 Renault Estafette, 1960 BMC Morris J4, and 1960 Commer FC also used the concept. In the United States, the Corvair-based Chevrolet Corvan cargo van and Greenbrier passenger van went so far as to copy the Type 2's rear-engine layout, using the Corvair's horizontally-opposed, air-cooled engine for power. Except for the Greenbrier and various 1950s–70s Fiat minivans, the Type 2 remained unique in being rear-engined. This was a disadvantage for the early "barndoor" Panel Vans, which couldn't easily be loaded from the rear due to the engine cover intruding on interior space, but generally advantageous in traction and interior noise.
The Type 2 was available as a:
Panel van, a delivery van without side windows or rear seats.
Nippen Tucket, available in six colours, with or without doors.
Walk-Through Panel Van, a delivery van without side windows or rear seats and cargo doors on both sides.
High Roof Panel Van (German: Hochdach), a delivery van with raised roof.
Kombi, from German: Kombinationskraftwagen (combination motor vehicle), with side windows and removable rear seats, both a passenger and a cargo vehicle combined.
Bus, also called a Volkswagen Caravelle, a van with more comfortable interior reminiscent of passenger cars since the third generation.
Samba-Bus, a van with skylight windows and cloth sunroof, first generation only, also known as a Deluxe Microbus. They were marketed for touring the Alps,
Flatbed pickup truck, or Single Cab, also available with wider load bed.
Crew cab pick-up, a flatbed truck with extended cab and two rows of seats, also called a Doka, from German: Doppelkabine.
Westfalia camping van, "Westy", with Westfalia roof and interior.
Adventurewagen camping van, with high roof and camping units from Adventurewagen.
Semi-camping van that can also still be used as a passenger car and transporter, sacrificing some camping comforts. "Multivan" or "Weekender", available from the third generation on.
Apart from these factory variants, there were a multitude of third-party conversions available, some of which were offered through Volkswagen dealers. They included, but were not limited to, refrigerated vans, hearses, ambulances, police vans, fire engines and ladder trucks, and camping van conversions by companies other than Westfalia. There were even 30 Klv 20 rail-going draisines built for Deutsche Bundesbahn in 1955.
The first generation of the Volkswagen Type 2 with the split windshield, informally called the Microbus, Splitscreen, or Splittie among modern fans, was produced from 8 March 1950 through the end of the 1967 model year. From 1950–1956, the T1 was built in Wolfsburg; from 1956, it was built at the completely new Transporter factory in Hanover. Like the Beetle, the first Transporters used the 1100 Volkswagen air cooled engine, an 1,131 cc (69.0 cu in), DIN-rated 18 kW (24 PS; 24 bhp), air-cooled flat-four cylinder 'boxer' engine mounted in the rear. This was upgraded to the 1200 – an 1,192 cc (72.7 cu in) 22 kW (30 PS; 30 bhp) in 1953. A higher compression ratio became standard in 1955; while an unusual early version of the 30 kW (41 PS; 40 bhp) engine debuted exclusively on the Type 2 in 1959. This engine proved to be so uncharacteristically troublesome that Volkswagen recalled all 1959 Transporters and replaced the engines with an updated version of the 30 kW engine. Any 1959 models that retain that early engine today are true survivors. Since the engine was totally discontinued at the outset, no parts were ever made available.
The early versions of the T1 until 1955 were often called the "Barndoor" (retrospectively called T1a since the 1990s), owing to the enormous rear engine cover, while the later versions with a slightly modified body (the roofline above the windshield is extended), smaller engine bay, and 15" roadwheels instead of the original 16" ones are nowadays called the T1b (again, only called this since the 1990s, based on VW's restrospective T1,2,3,4 etc. naming system.). From the 1964 model year, when the rear door was made wider (same as on the bay-window or T2), the vehicle could be referred to as the T1c. 1964 also saw the introduction of an optional sliding door for the passenger/cargo area instead of the outwardly hinged doors typical of cargo vans. This change arguably makes the 1964 Volkswagen the first true minivan, although the term wouldn't be coined for another two decades.
In 1962, a heavy-duty Transporter was introduced as a factory option. It featured a cargo capacity of 1,000 kg (2,205 lb) instead of the previous 750 kg (1,653 lb), smaller but wider 14" roadwheels, and a 1.5 Le, 31 kW (42 PS; 42 bhp) DIN engine. This was so successful that only a year later, the 750 kg, 1.2 L Transporter was discontinued. The 1963 model year introduced the 1500 engine – 1,493 cc (91.1 cu in) as standard equipment to the US market at 38 kW (52 PS; 51 bhp) DIN with an 83 mm (3.27 in) bore, 69 mm (2.72 in) stroke, and 7.8:1 compression ratio. When the Beetle received the 1.5 L engine for the 1967 model year, its power was increased to 40 kW (54 PS; 54 bhp) DIN.
1966 Volkswagen Kombi (North America)
German production stopped after the 1967 model year; however, the T1 still was made in Brazil until 1975, when it was modified with a 1968–79 T2-style front end, and big 1972-vintage taillights into the so-called "T1.5" and produced until 1996. The Brazilian T1s were not identical to the last German models (the T1.5 was locally produced in Brazil using the 1950s and 1960s-era stamping dies to cut down on retooling, alongside the Beetle/Fusca, where the pre-1965 body style was retained), though they sported some characteristic features of the T1a, such as the cargo doors and five-stud 205 mm (8.1 in) PCD) rims.
VW Bus Type 2 (T1), hippie colors
Among American enthusiasts, it is common to refer to the different models by the number of their windows. The basic Kombi or Bus is the 11-window (a.k.a. three-window bus because of three side windows) with a split windshield, two front cabin door windows, six rear side windows, and one rear window. The DeLuxe model featured eight rear side windows and two rear corner windows, making it the 15-window (not available in Europe). Meanwhile, the sunroof DeLuxe with its additional eight small skylight windows is, accordingly, the 23-window. From the 1964 model year, with its wider rear door, the rear corner windows were discontinued, making the latter two the 13-window and 21-window respectively. The 23- and later 21-window variants each carry the nickname 'Samba', or in Australia, officially 'Alpine'.
Certain models of the Volkswagen Type 2 played a role in an historic episode during the early 1960s, known as the Chicken War. France and West Germany had placed tariffs on imports of U.S. chicken. Diplomacy failed, and in January 1964, two months after taking office, President Johnson imposed a 25% tax (almost 10 times the average U.S. tariff) on potato starch, dextrin, brandy, and light trucks. Officially, the tax targeted items imported from Europe as approximating the value of lost American chicken sales to Europe.
In retrospect, audio tapes from the Johnson White House, revealed a quid pro quo unrelated to chicken. In January 1964, President Johnson attempted to convince United Auto Workers' president Walter Reuther not to initiate a strike just prior to the 1964 election, and to support the president's civil rights platform. Reuther, in turn, wanted Johnson to respond to Volkswagen's increased shipments to the United States.
The Chicken Tax directly curtailed importation of German-built Type 2s in configurations that qualified them as light trucks – that is, commercial vans (panel vans) and pickups. In 1964, U.S. imports of automobile trucks from West Germany declined to a value of $5.7 million – about one-third the value imported in the previous year. After 1971, Volkswagen cargo vans and pickup trucks, the intended targets, "practically disappeared from the U.S. market". While post-1971 Type 2 commercial vans and single-cab and double-cab pickups can be found in the United States today, they are exceedingly rare. As of 2009, the Chicken tax remains in effect.

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!
Some background:
The P-74 "Charger" was a fighter aircraft built by Lockheed for the United States Army Air Forces (USAAF). Its configuration was unusual as it was designed as a twin boom pusher configuration, where the propeller is mounted in the rear of the fuselage, pushing the aircraft forward.
The P-74 entered service with the USAAF in late 1944, its conception dated back to 1939 when the U.S. Army Air Corps requested with the Circular Proposal R40C domestic manufacturers to develop high performance fighter types, allowing (even demanding) unusual configurations. Lockheed did not respond immediately and missed the chance to sign a development contract in mid-1940 until early 1941. Twenty-three proposals were submitted to R40C, and after a fist selection of ideas three companies, Vultee with the large XP-54 Swoose Goose, Curtiss with its XP-55 Ascender and Northrop's XP-56 Black Bullet were able to secure prototype contracts.
Vultee eventually won the competition, but all these innovative new aircraft suffered from various flaws or development delays, missing various performance goals, so that none ever entered service.
In the meantime, Lockheed had been working on the 1939 request in the background on a private venture basis, as it was clear that by 1944 a successor to the company's own P-38 Lightning had to be offered to the USAAC.
The new North American P-51 Mustang was also a sharp competitor, esp. for the Pacific conflict theatre where long range was needed. This role was filled out very well by the P-38, but it was a relatively large and complicated aircraft, so an alternative with a single engine was strived for. Even though jet engines already showed their potential, it was clear that the requested range for the new type could only be achieved through a piston engine.
This aircraft became the XP-74, originally christened “Laelaps”, following Lockheed’s tradition, after a female Greek mythological dog who never failed to catch what she was hunting. It was presented as a mock-up to USAAC officials on August 8th 1942 and immediately found sponsorship: with the disappointing results from the XP-54,55 and 56 was immediately ushered into the prototype stage. Its name, though, was rejected, and the more common name “Charger” was adopted.
Just like Lockheed’s successful P-38 the XP-74 Charger was designed as a twin-boom aircraft, but it was driven by only a single Packard (License-built Rolls Royce Merlin) V-1650 pusher engine in the aft part of the fuselage. The tail was mounted rearward between two mid-wing booms, with a four-bladed 12-ft propeller between them. The design also included a "ducted wing section" developed by the NACA that enabled installation of cooling radiators and intercoolers in the wing root section.
The advantages of a pusher design are that the view forward is unobstructed and armament can be concentrated in the nose, while a major drawback is difficulty in escaping from the aircraft in an emergency, as the pilot could get drawn into the propeller blades. Lockheed deliberated between systems that would eject the pilot, or jettison the propeller or the engine, via a system of explosive bolts. Lockheed eventually installed an early ejector seat which was driven by pressurized air, combined with a mechanism that would blow the canopy off. The system was successfully tested in summer 1943, even though skepticism remained among pilots.
Initial armament comprised one 20mm Hispano cannon and four 12.7mm Browning machine guns, the same as in the P-38, but two machine guns were relocated from the nose into the front ends of the tail booms because of the new aircraft’s smaller overall dimensions.
The first prototype was ready in October 1943, with a different engine and heavier armor fitted. The second prototype was built to this specification from the start, which would become the serial production standard, the P-74A.
The P-74A used the new V-1650-9 engine, a version of the Merlin that included Simmons automatic supercharger boost control with water injection, allowing War Emergency Power as high as 2,218 hp (1,500 kW). Another change concerned the armament: a longer weapon range was deemed necessary, so the gun armament was changed into four 20mm Hispano cannons, two of the placed in the fuselage nose and one in each tail boom front end. Each gun was supplied with 250 RPG.
Alternatively, a nose installment with a single 37mm cannon and two 12.7mm Browning MGs was tested on the first prototype, but this arrangement was found to be less effective than the four 20mm cannons. Another factor that turned this option down was the more complicated logistics demands for three different calibers in one aircraft.
The P-74A was ready for service in summer 1944, but its deployment into the Pacific region took until December – the 5th Air Force first units replaced most of its P-38 and also early P-47Ds with the P-74A.These new aircraft had their first clashes with Japanese forces in January 1945.
The P-74 was used in a variety of roles. It was designed as an intreceptor against bombers, but its good range and handling at all altitudes made it suitable for tasks like fighter sweeps against enemy airfields, support for U.S. ground forces and protection of sea convoys and transport routes.
While the P-74 could not out-turn the A6M Zero and most other Japanese fighters when flying below 200 mph (320 km/h), its superior speed coupled with a good rate of climb meant that it could utilize energy tactics, making multiple high-speed passes at its target. Also, its focused firepower was deadly to lightly armored Japanese warplanes.
Because of its late service introduction, only 305 P-74s were ever produced until the end of hostilities, and they were exclusively used in the Pacific theatre. The P-74's service record shows mixed results, but usually because of misinformation. P-74s have been described as being harder to fly than traditional, single-engined aircraft, but this was because of inadequate training in the first few months of service.
Another drawback was the ejection seat system – it worked basically well, but the tank for the pressurized air turned out to be very vulnerable to enemy fire. Several P-74s literally exploded in midair after cannon fire hits, and this poeblem could only be cured when the tank section behind the cockpit received a more rigid structure and additional armor. Anyway, the P-74 was quickly retired after WWII, as the USAAF focussed on P-47 and P-51.

The kit and its assembly:
This whif was inspired by a CG rendition of a Saab J21 in a natural metal finish and with (spurious) USAAF markings, probably a skin for a flight simulator. Anyway, I was more or less enchanted by the NMF on the Saab – I had to build one, and it would become the P-74, the only USAF fighter code that had never been used.
The kit is the venerable Heller Saab J21A, an “old style” design with raised panel lines. But it is still around and affordable. No big mods were made to the kit during its transition into a USAAF fighter, even though I changed some minor things:
● Main landing gear was completely exchanged through struts from an Airfix A-1 Skyraider and the wheels from a Hasegawa P-51D; thin wire was added as hydraulic tubes
● New propeller blades: instead of the three-bladed original I added four much broader blades with square tips (from a Heller P-51D) to the original spinner
● Different exhaust stubs, which actually belong to a Spitfire Merlin (Special Hobby kit)
● Underfuselage flap was slightly opened
● A pilot figure was added to the nice cockpit
● The gun barrels were replaced with hollow styrene tubes
Painting and markings:
NMF was certain, but the rest…? I wanted to have a colorful aircraft, and eventually settled for a machine in the Pacific theatre of operations. When I browsed for options I eventually decided to apply broad black stripes on wings and fuselage, typical 5th Air Force markings that were used e. g. on P-47Ds and P-51Ds.
Overall design benchmark for my aircraft is a P-47D-28 of 310th FS/58th FG. The tail would be all white, and the rudder sported red and white stripes, early war insignia. The red nose trim and the deep yellow spinner were taken over from this aircraft, too. The blue individual code number is a personal addition, as well as the nose art, which was puzzled together from a Czech 'Perdubice' Meeting MiG-21 and leftover bits from a Pacific use P-51.
The aircraft was basically painted with Aluminum Metallizer (Humbrol 27002) and Polished Steel Metallizer (Modelmaster), and some panels were contrasted with Aluminum (Humbrol 56).
The anti-glare panel in front of the cockpit was painted in Olive Drab (Humbrol 66), the red nose trim with Humbrol 19. The tail was painted with a mix of Humbrol 34 & 196, for a very light grey, and later dry-painted with pure white.
The black ID stripes as well as the red and blue rudder trim were not painted, but rather created through decal sheet material (from TL Modellbau), cut to size and shape to fit into their respective places. The tail was a PITA, but for the black stripes this turned out to be very effective and convenient - an experiment that willcertainly see more future use.
Cockpit interior was painted in Humbrol 226 (Cockpit Green) and Zinc Chromate Green from Model Master, the landing gear wells received a chrome yellow primer (Humbrol 225) finish.
The landing gear struts were kept in bare Aluminum.
For weathering the kit received a rubbing treatment with grinded graphite, which adds a dark, metallic shine and emphasizes the kit’s raised panel lines. Some dry painting with Aluminum was added, too, simulating chipped paint on the leading edges, and on the black ID stripes some dark grey shading was added.
A relatively simple whif, but I love how the Saab 21 looks in the unusual, shiny NMF finish - and the USAAF markings with the prominent ID stripes suit it well, even though it looks a bit like a circus attraction now?

INSTRUCTIONS AVAILABLE FOR P558 SUPERDUTY - MULTIPLE CONFIGURATIONS
On September 24, 2015, Ford unveiled the 2017 Ford Super Duty line at the 2015 State Fair of Texas. he frame is made from 95% high strength steel and the body (like the contemporary F-150) is made from 6000 series aluminum alloy. For the first time since 1999, both the Super Duty and F-150 lines are constructed using the same cab.
For 2017 production, the Super Duty line shares its powertrain lineup with its 2016 predecessor: a 6.2L gasoline V8, 6.8L V10 (F-450 and above), with a 6.7L diesel V8 available in all versions. The 6.2L gasoline V8 engine remains at 385 hp but torque rises from 405 lb-ft to 430 lb-ft. Additionally, the gasoline V8 produces its max torque at over 700 rpm less than the previous 405 lb-ft engine. The 6.7L diesel engine also remains at the same 440 hp (323 kW) but torque increases from 860 lb-ft upwards to 925 lb-ft.
The 2020 Super Duty debuted at the 2019 Chicago Auto Show. It features a revised grille and tailgate design, new wheel options, and higher-quality interior materials for the Limited trim. A new 7.3-liter gasoline engine is available. Nicknamed "Godzilla", it makes 430 horsepower and 475 lb-ft of torque.
Cab configurations continue to be 2-Door Regular Cab, 4-Door Super Cab, and 4-Door Super Crew Cab, with Short Box (6' 9") and Long Box (8') bed lengths. The truck will be available in F-250, F-350, and F-450 pickup truck models, and F-350, F-450, and F-550 chassis cab models. All will be available in both 4X2 and 4X4 configurations. The F-350 will be the only model available in either Single Rear Wheel (SRW) or Dual Rear Wheel (DRW) configurations, the F-450 and F-550 will only be available in a Dual Rear Wheel (DRW) configuration, and the F-250 will only be available in a Single Rear Wheel configuration.

Some background:
The Hawker Furore was an evolutionary development of the successful Fury fighter. Like the Fury, the Furore was powered the liquid-cooled Rolls-Royce F.XI V-12 engine (later known as the Rolls-Royce Kestrel), which was also used by Hawker's new light bomber, the Hawker Hart.
The new fighter prototype first flew at Brooklands, Surrey, in March 1932, about a year after the Hawker Fury biplane had entered RAF service, and, in parallel, Hawker’s chief designer Sidney Camm also designed a monoplane version of the Fury, but it was held back since Rolls Royce was developing a new, more powerful engine at that time.
The Furore was a single-engine biplane and featured a modern all metal structure single bay wings and the Kestrel engine was enclosed by a smooth, streamlined cowling. But even though the new aircraft used many components from the Fury, it had a totally different look: The Furore had a novel configuration for a fighter, with the fuselage attached to the upper wing — somewhat like the 1914-designed German Gotha G.I bomber and the contemporary Handley Page Heyford heavy bomber. The lower wing was connected with to the fuselage through the landing gear struts, a pair of small pylons and by single struts between the outer wing sections. The fixed, spatted landing gear was integrated into the lower wing’s leading edge, and instead of the Fury’s tail skid the Furore was outfitted with a small wheel, which was spatted, too.
The rationale behind the unusual layout was the desire for a free field of view for the pilot, which was, in traditional designs, obscured by the upper wing. Another factor were improved aerodynamics through less struts, e.g. for the landing gear and between the wings, and attention was paid to reduce drag wherever possible. In the end, Furore and Fury had only their outlines in common, and maintenance of both types was very similar, but structurally the two types differed considerably from each other.
The armament was augmented to four 0.303 in (7.7 mm) machine guns: a synchronized pair fired through an innovative variable pitch three blade propeller (instead of the Fury’s wooden fixed-pitch two blade propeller), while two more of these weapons were integrated into the spat fairings, firing outside of the propeller arc.
Since Rolls Royce’s new engine was pending and in order to compare the Furore’s potential with the conservative Fury, the Air Ministry ordered at the start of 1933 a small initial production run for 21 aircraft. These machines, designated Furore Mk. I, were delivered in the course of early 1934 and distributed evenly among No. 25 and 43 squadron, which also operated the Hawker Fury as direct benchmark. One machine was kept at Hawker for further testing and development.
These trials soon showed that, despite the Furore’s slightly higher weight, the benefits from the aerodynamic cleaning effort outweighed this penalty. The improved firepower also spoke in favor of the Furore. However, the type’s handling was less appreciable, horizontal stability had suffered and the low ground clearance of the lower wing created an unexpected ground effect, which made landing the aircraft literally difficult. Furthermore, the unusual wing position resulted in an operational drawback: even though the pilot enjoyed an almost free, hemispherical field of view from the cockpit in flight, the view for- and downwards was hampered by the relative position of the upper wings and the cockpit, which made taxiing and especially landing – on top of the venturous ground effect – hazardous.
Despite these drawbacks, a second batch of 30 aircraft with some minor refinements (recognizable by longer spats) was ordered in late 1934 as Furore Mk. II, just a couple of weeks before Sidney Camm’s Fury monoplane design eventually came to official attention when Rolls-Royce presented their famous Merlin engine. The Fury monoplane’s design was then revised, according to Air Ministry specification F5/34, to become the prototype Hawker Hurricane. This highly successful type quickly replaced the RAF biplane fighters in frontline units from 1937 onwards, and from this point on, the small Furore fleet was quickly retired or used in liaison and meteorological duties 1940, when the type was retired.

The kit and its assembly:
This one is another contribution to the “RAF Centenary” Group Build at whatifmodelers.com. It was actually inspired by a Matchbox Handley Page Heyford in my stash – I looked at the box an asked myself “Why did you buy this…?”. However, the Heyford and its unique layout made me wonder how a contemporary fighter might have looked like? Looking for a potential conversion basis I stumbled upon the Hawker Fury biplane – its structure looked like a good basis.
Said and done, I organized a Matchbox Fury in the form of a Revell re-boxing. I was shocked to see, though, that this re-issue is of really poor quality, with lots of flash and even some sinkholes! I have no idea what Revell did to the originally very crisp Matchbox molds!?
Conversion work started with wing surgery: the upper wing lost a middle section, which was transplanted between the lower wings, which were cut off from their fuselage connector. The latter was used as a plug to fill the ventral gap between the lower wings’ original position.
Cockpit and tail were taken OOB (I just used a single pair of stabilizing struts instead of two), but I added a spine fairing behind the cockpit (a leftover piece from an Airfix P-61 drop tank) and mounted a taller windscreen.
The upper wings were then mounted directly to the fuselage, under the machine gun mounts. The radiator was placed into its original, ventral position. The lower wing then received a pair of spatted wheels (Eduard resin replacements for an Avia B.534), since I wanted to integrate them into the hull and reduce the overall number of struts. In a wake of more modernization, I also added a pair of machine gun gondolas (from a Gloster Gladiator) on top of them, and the spats were elongated and blended into the wings with 2C putty.
Mounting the lower wing freely under the fuselage was the biggest stunt – I eventually settled on using the Fury’s landing gear struts as connectors – they’d also ensure a proper height of the aircraft. Once they were in place, I added another pair of struts between the fuselage and the lower wing, for a proper angle of attack. After letting this wobbly affair dry thoroughly, the wings were connected with four tailor-made single struts, created from the OOB N-shaped struts. The result is quite stable!
The original wooden, two-blade propeller was replaced by a more modern three-blade propeller with a round spinner; it comes from an Airfix Westland Whirlwind, but had to be modified in order to fit onto the Fury’s nose. Internally, a styrene tube and a metal axis were added.
After the good experience with my recent TR.2 build, the rigging was done as a final step after painting and applying varnish – as per usual, I used dark grey styrene material and white glue.
Painting and markings:
Not many choices here – either a colorful aircraft in overall silver, or a toned-down, camouflaged livery. I settled for the latter, in a typical 1938-39 livery in Dark Green and Dark Earth (Tamiya XF-61 and Humbrol 29). The fuselage and stabilizer undersurfaces were painted in aluminum (Revell 99), while the outer wings became black (Revell 09) and white (Humbrol 22, with a little 147 added).
The cockpit interior was painted in Tar Black (Revell 06), while the spinner became black and Dark Earth. The propeller blades received bare metal front sides, while the rear became black, with yellow tips.
After a black ink wash the model received a post-shading treatment. The decals were puzzled together from the scrap box, e.g. with roundels from an Italeri Tornado, medium sea grey code letters from Xtradecal and serials and some other markings from an Airfix Hurricane. The yellow trim as flight marking on the spats is the only extraordinary addition to the otherwise sombre look.
After some light soot stains around the exhausts, the kit was sealed with matt acrylic varnish from the rattle can. The final step was the rigging, which I tried to keep at a plausible minimum.
A thorough conversion, even though almost the complete original Fury kit could be used! And the result is really ambiguous – on one side, the resulting Furore looks both plausible and very Thirties, like one of those many weird designs that were spawned during the transitional era between biplanes and monoplanes. The build was intended to look like the missing link between the Fury and the Hurricane, and I think that I achieved that. On the other side, the “Heyford effect” takes full effect: despite being based on a sleek and elegant aircraft, and with no major additions, the “re-arranged” Furore looks quite bulky and very massive.

A Unique Configuration of 1850 facades
A Bird-eye View of Downtown Delphi in the 1850s
Dan McCain, Paul Brandenburg, Charkes Gerard & Tom Castaldi, successfully campaigned for the importance & practicality of using the historic business named & facades from Delphi's Canal Era. Charles Gerard shouldered the task of providing the architects enough authentic photos & description to faithfully represent a section of an 1850s street front in Delphi.
Understanding, architectural license has been taken to accommodate the dimensions of the Canal Center & its surrounds, but this benchmark decision allows today's onlooker to step into early, virile Delphi, a hustling trade center, rather than a generic facsimile. With the completion of the Wabash & Eric Canal to Delphi in 1840 a steady stream of fashions & new products turned Delphi into a cultural outpost in the Indiana wilderness.
The Keelmen of Tyne and Wear were a group of men who worked on the keels, large boats that carried the coal from the banks of both rivers to the waiting collier ships. Because of the shallowness of both rivers, it was difficult for ships of any significant draught to move up river and load with coal from the place where the coal reached the riverside. Thus the need for shallow-draught keels to transport the coal to the waiting ships. The keelmen formed a close-knit and colourful community on both rivers until their eventual demise late in the nineteenth century.
Beginnings of the coal trade
Coal began to be exported from the River Tyne from the mid-thirteenth century onwards. The first recorded shipment of coal from the River Wear was in 1396. The pits from which coal was then exported were near the riverside so that as little effort as possible was required to load it. The coal was carried to London and elsewhere in colliers; small wooden sailing ships that sailed down the east coast. At this time neither the Tyne nor the Wear were easily navigable for ships of significant draught. The mouth of the Tyne was obstructed by Herd Sands, Bellehues Rock and a bar that ran across the mouth of the river. Further up river a ship might run aground in various shallows and the stone bridge at Newcastle prevented colliers from reaching coal deposits further up river. Both rivers were very shallow near the banks, which made the approach difficult so coal was loaded into the shallow-draught keels to transport it down river.
The keels
The keels were wooden boats with a pointed stern, so that the bow and stern looked almost the same. They were of shallow draught so that when fully loaded they drew only four and a half feet. The keels were forty feet long and at least 19 feet wide amidships: a very broad configuration. They were carvel-built (smooth sided) and generally of oak, often with elm used below the waterline. In 1266 the standard load of a keel was set at 20 chaldrons (wagonloads) or approximately 17 tons. After 1497 the keel load was frequently increased, until in 1635 it was set at 21.1 tons. A chaldron was a horse-drawn wagon containing 17 cwt of coal. Keels were supposed to be measured by the Kings Commissioners and given a load mark to show when they were full.
Early keels were propelled with a large oar, handled by all the crew except the skipper; they had no rudder and were steered by a second oar or "swape" over the stern. The crew worked with the flow of the river tides where practicable. Later the oars were supplemented by a mast with a square sail attached to a yard, and latterly with a large spritsail and staysail, though the oars were still used to row when the wind was not favourable. There were also two eighteen-foot, iron-shod poles ("puoys") for polling the keel through any shallows. The floor of the hold was only two feet below the gunwale to allow for easy loading. The coal was piled high above the top of the hold with wooden boards used to prevent the cargo from sliding. Each keel was manned by a skipper, two crewmen and a boy, known as a 'pee dee' 'P. D.' or 'paydee'. While it has been stated that the meaning of this title is unknown, it might have developed from an earlier use of 'peedee' meaning "footboy", or "groom", from Latin pede, "on foot". As the railways started to take away the keelmen's trade, most skippers discontinued the employment of a boy to save on their salary. The two crewmen were invariably called the 'bullies' ("bully" here meaning "brother", "comrade"). Many keels had a small after-cabin or "huddick", fitted with a stove, where the crew could sleep.
Work and conditions
Keelmen loaded coal into the keel's hold from a "spout" or riverside chute. The keel would then be taken down river on the ebb tide using oars, or sail if the wind was favourable, and taken alongside the waiting collier where the crew would shovel the coal into the collier, working even after darkness. This could be arduous due to the difference in height between the keel's gunwale and the collier's deck. When keelmen struck in 1819 one of their demands was an extra shilling per keel per foot that the side of the collier exceeded five feet. After a time colliers were constructed in such a manner as to make it easier to load coal into them. After loading the keelmen would return for another load if there was daytime left and tides allowed. They were paid by the "tide"; i.e. by each trip between the ship and the staith, irrespective of distance. By the mid 19th century the usual fee was one guinea, including loading, which the keel's owner would split amongst the three crew in nearly equal shares, retaining only around 8d. per tide over and above the other shares. Before the railways began to harm the trade, a keel owner would expect to make around ten "tides" a week.
Keelmen were traditionally bound to employment for a year, the binding day normally being Christmas Day but employment tended to be seasonal with hardly any work in winter. The availability of work was often affected by the weather, if ships were unable to come into the river, and also by the supply of coal from the pits. Strikes might affect output and wily pit owners would sometimes curtail production to keep prices high. As a result, keelmen could spend long periods without work, during which they would have to live on credit or find employment in clearing wrecks and sand banks from the river. The Tyneside keelmen formed an independent society in 1556 but were never incorporated, probably because the Newcastle Hostmen feared their becoming too powerful. The Wearside keelmen were finally incorporated by Act of Parliament in 1792.
The Tyneside keelmen lived in the Sandgate area, outside the city walls, one of the poorest and most overcrowded parts of the city, made up of many narrow alleys. John Baillie, writing in the late 18th century, said that they "live almost entirely upon flesh-meat and flour, of the best kinds, which their strong exertions in their employment require." They were known by some as a close-knit group of aggressive, hard-drinking men: John Wesley, after visiting Newcastle, described them as much given to drunkenness and swearing. Baillie said that this reputation was entirely undeserved: the keelmen had a "rough" way of expressing themselves, and were loud and vociferous "from the practice of hailing one another on the river, especially in the night tides", but "they scorn to show what they think incivility or rudeness to any person".[8] Despite this, in the mid 19th century they were described as "a proverbially unintelligent, ignorant and intemperate set of men. One keelman, it used to be said, could drink out three pitmen".
For their Sunday best clothing the keelmen often wore a distinctive blue coat or short blue jacket: this was accompanied by a flat-brimmed black hat, yellow waistcoat and white shirt, and legwear described as either slate-grey trousers or blue stockings and flannel breeches. In the 18th century keelmen were identifiable by the blue bonnet many of them wore at work, later replaced by a sou'wester. In the 1840s they were described as wearing "a peculiar costume, consisting of a large jacket, or rather doublet, with loose breeches, made very wide at the knee, and not descending further". The trade of keelmen tended to be passed on from father to son, the son working as an apprentice on a keel until considered old enough and strong enough to be a crewman. Most men were unfit to continue the physically very demanding work into their forties. By 1700 there were 1,600 keelmen working on the Tyne in 400 keels. Not all were local: there was a significant number of Scottish keelmen who returned home in the winter when trade was slack.
Disputes with the Hostmen
The Tyneside keelmen were employed by the Newcastle Hostmen and were often in dispute with their employers. They went on strike in 1709, 1710, 1740 and 1750. One grievance held by the keelmen was that the Hostmen, in order to avoid custom duties, would deliberately overload the keels. Duty was paid on each keel-load, so that it paid the owner to load as much coal as possible. This meant that the keel-load gradually increased from 16 tons in 1600 to 21.25 tons in 1695. As the keelmen were paid by the keel-load, they had to work considerably harder for the same pay. Even after the keel-load had been standardised, there were cases of keel owners illegally enlarging the holds to carry more coal, as much as 26.5 tons. In 1719 and 1744, the Tyneside keelmen went on strike in protest at this 'overmeasure'. The 1750 strike was also against 'overmeasure', as well as against 'can-money', the practice of paying part of the keelmen's wages in drink that had to be consumed at 'can-houses', pubs owned by the employers.
Expansion of the Wear coal trade
The coal export trade from the Wear was slow to develop, but by the seventeenth century there was a thriving trade in exporting coal from the Durham coalfield via the River Wear. The tonnage however was much smaller than on the Tyne; in 1609, 11,648 tons were exported from the Wear compared with 239,000 tons exported from the Tyne. This imbalance changed dramatically during the English Civil War because of the Parliamentarian blockade of the Tyne and their encouragement of the Wearside merchants to make up for the subsequent shortfall in coal for London. Coal exports from the Wear increased by an enormous amount, causing a similar increase in the number of keelmen employed on the river. By time of the Restoration in 1660, trade on the Tyne had recovered, but the river was now only exporting a third more coal than the Wear.
The Keelmen's Hospital
In 1699 the keelmen of Newcastle decided to build the Keelmen's Hospital, a charitable foundation for sick and aged keelmen and their families. The keelmen agreed to contribute one penny a tide from the wages of each keel's crew and Newcastle Corporation made land available in Sandgate. The hospital was completed in 1701 at a cost of £2,000. It consisted of fifty chambers giving onto a cloister enclosing a grass court. One matter of contention relating to the hospital was that the funds for its maintenance were kept in the control of the Hostmen, lest they be used as a strike fund by the keelmen. The hospital building still remains in City Road, Newcastle, and was used for student accommodation until recently. The building is now on the Heritage at Risk register. It has stood vacant since the closure of the student accommodation, and was added to the register in 2009.
Impressment in the Royal Navy
Because of their experience of handling boats, the keelmen were considered useful in times of war when the Royal Navy required seamen for its warships. During the French wars of the late eighteenth century, the Naval Impress Service would have liked to impress as many keelmen as possible, but the keelmen were officially protected from impressment. However, in 1803, during a time of crisis, the Tyne Regulating Officer captured 53 keelmen with the intention of impressing them into the navy despite their exemption. In retaliation, their wives took up whatever was handy (shovels, pans, rolling pins) and marched to North Shields intent on using any means to rescue their men, whilst the rest of the keelmen went on strike until the captured men were released. A compromise was reached so that 80 ‘volunteers’ (one in ten keelmen) would be accepted into the navy and the rest would be exempted from impressment. A levy was to be paid by the coal-owners and keelmen to provide a bounty for the keelmen who joined the navy. A similar situation existed on the Wear, except that the keelmen there were treated less generously. They had to provide a similar quota of recruits with two landsmen counting as one prime sailor.
Coal staiths
About 1750 a new development began to be used on the Tyne. New pits were being sunk further and further away from the river and coal was being brought to the riverbank via wagon ways. Once there, in places accessible by colliers, coal staiths were built to allow coal to be dropped directly into the holds of the colliers without the need for keels. The staiths were short piers that projected out over the river and allowed coal wagons to run on rails to the end. Colliers would moor alongside the end of the staiths and, initially, the coal from the wagons was emptied down chutes into the colliers’ holds. Later, to avoid breakage of the coal, the coal wagons were lowered onto the decks of the colliers and were unloaded there. This was the beginning of the end for the keelmen and they realised the threat that the coal staiths posed. Strikes and riots resulted whenever new staiths were opened. In 1794 the Tyneside keelmen went on strike against the use of staiths for loading coal.
Because of the shallowness of the Tyne, the use of coal staiths did not entirely eliminate the need for keels. The amount that the staiths projected into the river was limited so as not to obstruct river traffic, so that the staiths ended in shallow water. As colliers were loaded their draught would deepen until often they were no longer able to continue loading from the staiths. In such cases the colliers would have to move into deeper water and the loading would be completed using keels.
Until 1800, the most productive pits were situated upriver from Newcastle, and colliers could not pass the bridge there to load coal. After 1800, coal production switched to further down river, where coal staiths could be used. Already by 1799, the number of keels working on the Tyne was 320 compared with 500 at the peak of their use. At this time, the Wear, with a smaller output of coal, employed 520 keels. Coal staiths were not introduced on the Wear until 1812, but were resisted just as strongly by the keelmen there. They rioted in 1815 in protest at coal being loaded via coal staiths.
Steam tugs
Another threat to the livelihood of the keelmen was the development of steam tugs. During a ten-week strike by the keelmen of both Tyne and Wear against the use of coal staiths, the keel owners installed one of the newly developed steam locomotives in a keel equipped with paddle wheels. The keel was not only able to propel itself, but was able to tow a string of other keels behind it. By 1830, Marshall's shipyard in South Shields had begun to manufacture steam tugs, for the Tyne and for further afield. This development did not threaten the livelihood of the keelmen as completely as the development of the coal staiths.
Improvements in river navigation
As mentioned above, the reason for employing keelmen was the poor state of the navigation on the Tyne and Wear, which prevented ships from moving up river without danger of grounding. As time went by this situation gradually worsened. Colliers arriving at the river mouth would have a ballast of sand that had to be disposed of. The correct method of doing this was to deposit the sand on specified areas on the riverbank provided for the purpose or by depositing the sand in the sea. The Wear had ballast keels that were used to unload the ballast from colliers and take it out to sea. There were penalties for depositing ballast in the river, but this often occurred. The result was that the riverbed became silted up, causing even more navigational difficulties. Additionally, industry on the riverbanks often deposited its waste products in the river. The situation on the Tyne became so bad that in 1850 the Tyne Navigation Act was passed, which gave control of the river to the Tyne Improvement Commission. This body began an extensive program of dredging to substantially deepen the riverbed. This program was completed in 1888 so that the largest colliers could pass right up to Newcastle and beyond. This deepening of the river meant that colliers could load coal from the staiths without the need for keels to complete the work. In 1876 the existing bridge at Newcastle was replaced by the Swing Bridge, which rotated to allow ships to pass up and down river. This allowed colliers to be loaded from staiths above Newcastle and so further sealed the fate of the keelmen.
The Wear Improvement Bill was passed in 1717, creating the River Wear Commission. Building was started on a south pier at the river mouth in 1723 and continued for many years. A north pier was completed in 1797. The piers were intended to improve the flow of water and prevent the river from silting up. The river was dredged in 1749 to improve access, but the use of keels continued undiminished until the introduction of coal staiths in 1813. In 1831 a new harbour was opened at Seaham, further down the Durham coast. This diverted much of the Durham coal away from Sunderland and further threatened the existence of the Wearside keelmen. In 1837 a North Dock was completed at the mouth of the Wear to load colliers and in 1850 a huge South Dock was completed with room for 250 vessels. These loading facilities made keels unnecessary except for inaccessible pits far up river. On the Tyne, three large docks were also constructed for loading coal: Northumberland Dock in 1857; Tyne Dock in 1859; Albert Edward Dock in 1884.
Final demise
By the mid-nineteenth century, less than a fifth of the pits on the Tyne and Wear were using keels to load coal. The introduction of coal staiths and steam tugs had already severely diminished the number of keelmen. The new docks with their efficient coal loading facilities brought the final demise of the keels and the men who worked them. The last few keels survived until the closing years of the 19th century, though by 1889 a writer noted that though some keelmen were still carrying out coal loading, "steamboats now do the work; keels are towed to and from the ships". "It's them steamers that's brust up the keelmen," the last keelman in the Keelmen's Hospital said in 1897, "it's a bonny bad job, but it cannot be helped".
The second half of the nineteenth century was a time of rapid industrial growth on Tyneside and Wearside, so that the keelmen would be readily absorbed within other industries. They are now just a distant memory with little to remind us of them, apart from the Keelmen's Hospital, which still stands in Newcastle, and the well-known local songs "The Keel Row" and "Cushie Butterfield."
Newcastle upon Tyne, or simply Newcastle is a cathedral city and metropolitan borough in Tyne and Wear, England. It is located on the River Tyne's northern bank, opposite Gateshead to the south. It is the most populous settlement in the Tyneside conurbation and North East England.
Newcastle developed around a Roman settlement called Pons Aelius, the settlement became known as Monkchester before taking on the name of a castle built in 1080 by William the Conqueror's eldest son, Robert Curthose. It was one of the world's largest ship building and repair centres during the industrial revolution. Newcastle was part of the county of Northumberland until 1400, when it separated and formed a county of itself. In 1974, Newcastle became part of Tyne and Wear. Since 2018, the city council has been part of the North of Tyne Combined Authority.
The history of Newcastle upon Tyne dates back almost 2,000 years, during which it has been controlled by the Romans, the Angles and the Norsemen amongst others. Newcastle upon Tyne was originally known by its Roman name Pons Aelius. The name "Newcastle" has been used since the Norman conquest of England. Due to its prime location on the River Tyne, the town developed greatly during the Middle Ages and it was to play a major role in the Industrial Revolution, being granted city status in 1882. Today, the city is a major retail, commercial and cultural centre.
Roman settlement
The history of Newcastle dates from AD 122, when the Romans built the first bridge to cross the River Tyne at that point. The bridge was called Pons Aelius or 'Bridge of Aelius', Aelius being the family name of Roman Emperor Hadrian, who was responsible for the Roman wall built across northern England along the Tyne–Solway gap. Hadrian's Wall ran through present-day Newcastle, with stretches of wall and turrets visible along the West Road, and at a temple in Benwell. Traces of a milecastle were found on Westgate Road, midway between Clayton Street and Grainger Street, and it is likely that the course of the wall corresponded to present-day Westgate Road. The course of the wall can be traced eastwards to the Segedunum Roman fort at Wallsend, with the fort of Arbeia down-river at the mouth of the Tyne, on the south bank in what is now South Shields. The Tyne was then a wider, shallower river at this point and it is thought that the bridge was probably about 700 feet (210 m) long, made of wood and supported on stone piers. It is probable that it was sited near the current Swing Bridge, due to the fact that Roman artefacts were found there during the building of the latter bridge. Hadrian himself probably visited the site in 122. A shrine was set up on the completed bridge in 123 by the 6th Legion, with two altars to Neptune and Oceanus respectively. The two altars were subsequently found in the river and are on display in the Great North Museum in Newcastle.
The Romans built a stone-walled fort in 150 to protect the river crossing which was at the foot of the Tyne Gorge, and this took the name of the bridge so that the whole settlement was known as Pons Aelius. The fort was situated on a rocky outcrop overlooking the new bridge, on the site of the present Castle Keep. Pons Aelius is last mentioned in 400, in a Roman document listing all of the Roman military outposts. It is likely that nestling in the shadow of the fort would have been a small vicus, or village. Unfortunately, no buildings have been detected; only a few pieces of flagging. It is clear that there was a Roman cemetery near Clavering Place, behind the Central station, as a number of Roman coffins and sarcophagi have been unearthed there.
Despite the presence of the bridge, the settlement of Pons Aelius was not particularly important among the northern Roman settlements. The most important stations were those on the highway of Dere Street running from Eboracum (York) through Corstopitum (Corbridge) and to the lands north of the Wall. Corstopitum, being a major arsenal and supply centre, was much larger and more populous than Pons Aelius.
Anglo-Saxon development
The Angles arrived in the North-East of England in about 500 and may have landed on the Tyne. There is no evidence of an Anglo-Saxon settlement on or near the site of Pons Aelius during the Anglo-Saxon age. The bridge probably survived and there may well have been a small village at the northern end, but no evidence survives. At that time the region was dominated by two kingdoms, Bernicia, north of the Tees and ruled from Bamburgh, and Deira, south of the Tees and ruled from York. Bernicia and Deira combined to form the kingdom of Northanhymbra (Northumbria) early in the 7th century. There were three local kings who held the title of Bretwalda – 'Lord of Britain', Edwin of Deira (627–632), Oswald of Bernicia (633–641) and Oswy of Northumbria (641–658). The 7th century became known as the 'Golden Age of Northumbria', when the area was a beacon of culture and learning in Europe. The greatness of this period was based on its generally Christian culture and resulted in the Lindisfarne Gospels amongst other treasures. The Tyne valley was dotted with monasteries, with those at Monkwearmouth, Hexham and Jarrow being the most famous. Bede, who was based at Jarrow, wrote of a royal estate, known as Ad Murum, 'at the Wall', 12 miles (19 km) from the sea. It is thought that this estate may have been in what is now Newcastle. At some unknown time, the site of Newcastle came to be known as Monkchester. The reason for this title is unknown, as we are unaware of any specific monasteries at the site, and Bede made no reference to it. In 875 Halfdan Ragnarsson, the Danish Viking conqueror of York, led an army that attacked and pillaged various monasteries in the area, and it is thought that Monkchester was also pillaged at this time. Little more was heard of it until the coming of the Normans.
Norman period
After the arrival of William the Conqueror in England in 1066, the whole of England was quickly subjected to Norman rule. However, in Northumbria there was great resistance to the Normans, and in 1069 the newly appointed Norman Earl of Northumbria, Robert de Comines and 700 of his men were killed by the local population at Durham. The Northumbrians then marched on York, but William was able to suppress the uprising. That same year, a second uprising occurred when a Danish fleet landed in the Humber. The Northumbrians again attacked York and destroyed the garrison there. William was again able to suppress the uprising, but this time he took revenge. He laid waste to the whole of the Midlands and the land from York to the Tees. In 1080, William Walcher, the Norman bishop of Durham and his followers were brutally murdered at Gateshead. This time Odo, bishop of Bayeux, William's half brother, devastated the land between the Tees and the Tweed. This was known as the 'Harrying of the North'. This devastation is reflected in the Domesday Book. The destruction had such an effect that the North remained poor and backward at least until Tudor times and perhaps until the Industrial Revolution. Newcastle suffered in this respect with the rest of the North.
In 1080 William sent his eldest son, Robert Curthose, north to defend the kingdom against the Scots. After his campaign, he moved to Monkchester and began the building of a 'New Castle'. This was of the "motte-and-bailey" type of construction, a wooden tower on top of an earthen mound (motte), surrounded by a moat and wooden stockade (bailey). It was this castle that gave Newcastle its name. In 1095 the Earl of Northumbria, Robert de Mowbray, rose up against the king, William Rufus, and Rufus sent an army north to recapture the castle. From then on the castle became crown property and was an important base from which the king could control the northern barons. The Northumbrian earldom was abolished and a Sheriff of Northumberland was appointed to administer the region. In 1091 the parish church of St Nicholas was consecrated on the site of the present Anglican cathedral, close by the bailey of the new castle. The church is believed to have been a wooden building on stone footings.
Not a trace of the tower or mound of the motte and bailey castle remains now. Henry II replaced it with a rectangular stone keep, which was built between 1172 and 1177 at a cost of £1,444. A stone bailey, in the form of a triangle, replaced the previous wooden one. The great outer gateway to the castle, called 'the Black Gate', was built later, between 1247 and 1250, in the reign of Henry III. There were at that time no town walls and when attacked by the Scots, the townspeople had to crowd into the bailey for safety. It is probable that the new castle acted as a magnet for local merchants because of the safety it provided. This in turn would help to expand trade in the town. At this time wool, skins and lead were being exported, whilst alum, pepper and ginger were being imported from France and Flanders.
Middle Ages
Throughout the Middle Ages, Newcastle was England's northern fortress, the centre for assembled armies. The Border war against Scotland lasted intermittently for several centuries – possibly the longest border war ever waged. During the civil war between Stephen and Matilda, David 1st of Scotland and his son were granted Cumbria and Northumberland respectively, so that for a period from 1139 to 1157, Newcastle was effectively in Scottish hands. It is believed that during this period, King David may have built the church of St Andrew and the Benedictine nunnery in Newcastle. However, King Stephen's successor, Henry II was strong enough to take back the Earldom of Northumbria from Malcolm IV.
The Scots king William the Lion was imprisoned in Newcastle, in 1174, after being captured at the Battle of Alnwick. Edward I brought the Stone of Scone and William Wallace south through the town and Newcastle was successfully defended against the Scots three times during the 14th century.
Around 1200, stone-faced, clay-filled jetties were starting to project into the river, an indication that trade was increasing in Newcastle. As the Roman roads continued to deteriorate, sea travel was gaining in importance. By 1275 Newcastle was the sixth largest wool exporting port in England. The principal exports at this time were wool, timber, coal, millstones, dairy produce, fish, salt and hides. Much of the developing trade was with the Baltic countries and Germany. Most of the Newcastle merchants were situated near the river, below the Castle. The earliest known charter was dated 1175 in the reign of Henry II, giving the townspeople some control over their town. In 1216 King John granted Newcastle a mayor[8] and also allowed the formation of guilds (known as Mysteries). These were cartels formed within different trades, which restricted trade to guild members. There were initially twelve guilds. Coal was being exported from Newcastle by 1250, and by 1350 the burgesses received a royal licence to export coal. This licence to export coal was jealously guarded by the Newcastle burgesses, and they tried to prevent any one else on the Tyne from exporting coal except through Newcastle. The burgesses similarly tried to prevent fish from being sold anywhere else on the Tyne except Newcastle. This led to conflicts with Gateshead and South Shields.
In 1265, the town was granted permission to impose a 'Wall Tax' or Murage, to pay for the construction of a fortified wall to enclose the town and protect it from Scottish invaders. The town walls were not completed until early in the 14th century. They were two miles (3 km) long, 9 feet (2.7 m) thick and 25 feet (7.6 m) high. They had six main gates, as well as some smaller gates, and had 17 towers. The land within the walls was divided almost equally by the Lort Burn, which flowed southwards and joined the Tyne to the east of the Castle. The town began to expand north of the Castle and west of the Lort Burn with various markets being set up within the walls.
In 1400 Henry IV granted a new charter, creating a County corporate which separated the town, but not the Castle, from the county of Northumberland and recognised it as a "county of itself" with a right to have a sheriff of its own. The burgesses were now allowed to choose six aldermen who, with the mayor would be justices of the peace. The mayor and sheriff were allowed to hold borough courts in the Guildhall.
Religious houses
During the Middle Ages a number of religious houses were established within the walls: the first of these was the Benedictine nunnery of St Bartholomew founded in 1086 near the present-day Nun Street. Both David I of Scotland and Henry I of England were benefactors of the religious house. Nothing of the nunnery remains now.
The friary of Blackfriars, Newcastle (Dominican) was established in 1239. These were also known as the Preaching Friars or Shod Friars, because they wore sandals, as opposed to other orders. The friary was situated in the present-day Friars Street. In 1280 the order was granted royal permission to make a postern in the town walls to communicate with their gardens outside the walls. On 19 June 1334, Edward Balliol, claimant to be King of Scotland, did homage to King Edward III, on behalf of the kingdom of Scotland, in the church of the friary. Much of the original buildings of the friary still exist, mainly because, after the Dissolution of the Monasteries the friary of Blackfriars was rented out by the corporation to nine of the local trade guilds.
The friary of Whitefriars (Carmelite) was established in 1262. The order was originally housed on the Wall Knoll in Pandon, but in 1307 it took over the buildings of another order, which went out of existence, the Friars of the Sac. The land, which had originally been given by Robert the Bruce, was situated in the present-day Hanover Square, behind the Central station. Nothing of the friary remains now.
The friary of Austinfriars (Augustinian) was established in 1290. The friary was on the site where the Holy Jesus Hospital was built in 1682. The friary was traditionally the lodging place of English kings whenever they visited or passed through Newcastle. In 1503 Princess Margaret, eldest daughter of Henry VII of England, stayed two days at the friary on her way to join her new husband James IV of Scotland.
The friary of Greyfriars (Franciscans) was established in 1274. The friary was in the present-day area between Pilgrim Street, Grey Street, Market Street and High Chare. Nothing of the original buildings remains.
The friary of the Order of the Holy Trinity, also known as the Trinitarians, was established in 1360. The order devoted a third of its income to buying back captives of the Saracens, during the Crusades. Their house was on the Wall Knoll, in Pandon, to the east of the city, but within the walls. Wall Knoll had previously been occupied by the White Friars until they moved to new premises in 1307.
All of the above religious houses were closed in about 1540, when Henry VIII dissolved the monasteries.
An important street running through Newcastle at the time was Pilgrim Street, running northwards inside the walls and leading to the Pilgrim Gate on the north wall. The street still exists today as arguably Newcastle's main shopping street.
Tudor period
The Scottish border wars continued for much of the 16th century, so that during that time, Newcastle was often threatened with invasion by the Scots, but also remained important as a border stronghold against them.
During the Reformation begun by Henry VIII in 1536, the five Newcastle friaries and the single nunnery were dissolved and the land was sold to the Corporation and to rich merchants. At this time there were fewer than 60 inmates of the religious houses in Newcastle. The convent of Blackfriars was leased to nine craft guilds to be used as their headquarters. This probably explains why it is the only one of the religious houses whose building survives to the present day. The priories at Tynemouth and Durham were also dissolved, thus ending the long-running rivalry between Newcastle and the church for control of trade on the Tyne. A little later, the property of the nunnery of St Bartholomew and of Grey Friars were bought by Robert Anderson, who had the buildings demolished to build his grand Newe House (also known as Anderson Place).
With the gradual decline of the Scottish border wars the town walls were allowed to decline as well as the castle. By 1547, about 10,000 people were living in Newcastle. At the beginning of the 16th century exports of wool from Newcastle were more than twice the value of exports of coal, but during the century coal exports continued to increase.
Under Edward VI, John Dudley, Duke of Northumberland, sponsored an act allowing Newcastle to annexe Gateshead as its suburb. The main reason for this was to allow the Newcastle Hostmen, who controlled the export of Tyne coal, to get their hands on the Gateshead coal mines, previously controlled by the Bishop of Durham. However, when Mary I came to power, Dudley met his downfall and the decision was reversed. The Reformation allowed private access to coal mines previously owned by Tynemouth and Durham priories and as a result coal exports increase dramatically, from 15,000 tons in 1500 to 35,000 tons in 1565, and to 400,000 tons in 1625.
The plague visited Newcastle four times during the 16th century, in 1579 when 2,000 people died, in 1589 when 1700 died, in 1595 and finally in 1597.
In 1600 Elizabeth I granted Newcastle a charter for an exclusive body of electors, the right to elect the mayor and burgesses. The charter also gave the Hostmen exclusive rights to load coal at any point on the Tyne. The Hostmen developed as an exclusive group within the Merchant Adventurers who had been incorporated by a charter in 1547.
Stuart period
In 1636 there was a serious outbreak of bubonic plague in Newcastle. There had been several previous outbreaks of the disease over the years, but this was the most serious. It is thought to have arrived from the Netherlands via ships that were trading between the Tyne and that country. It first appeared in the lower part of the town near the docks but gradually spread to all parts of the town. As the disease gained hold the authorities took measures to control it by boarding up any properties that contained infected persons, meaning that whole families were locked up together with the infected family members. Other infected persons were put in huts outside the town walls and left to die. Plague pits were dug next to the town's four churches and outside the town walls to receive the bodies in mass burials. Over the course of the outbreak 5,631 deaths were recorded out of an estimated population of 12,000, a death rate of 47%.
In 1637 Charles I tried to raise money by doubling the 'voluntary' tax on coal in return for allowing the Newcastle Hostmen to regulate production and fix prices. This caused outrage amongst the London importers and the East Anglian shippers. Both groups decided to boycott Tyne coal and as a result forced Charles to reverse his decision in 1638.
In 1640 during the Second Bishops' War, the Scots successfully invaded Newcastle. The occupying army demanded £850 per day from the Corporation to billet the Scottish troops. Trade from the Tyne ground to a halt during the occupation. The Scots left in 1641 after receiving a Parliamentary pardon and a £4,000,000 loan from the town.
In 1642 the English Civil War began. King Charles realised the value of the Tyne coal trade and therefore garrisoned Newcastle. A Royalist was appointed as governor. At that time, Newcastle and King's Lynn were the only important seaports to support the crown. In 1644 Parliament blockaded the Tyne to prevent the king from receiving revenue from the Tyne coal trade. Coal exports fell from 450,000 to 3,000 tons and London suffered a hard winter without fuel. Parliament encouraged the coal trade from the Wear to try to replace that lost from Newcastle but that was not enough to make up for the lost Tyneside tonnage.
In 1644 the Scots crossed the border. Newcastle strengthened its defences in preparation. The Scottish army, with 40,000 troops, besieged Newcastle for three months until the garrison of 1,500 surrendered. During the siege, the Scots bombarded the walls with their artillery, situated in Gateshead and Castle Leazes. The Scottish commander threatened to destroy the steeple of St Nicholas's Church by gunfire if the mayor, Sir John Marley, did not surrender the town. The mayor responded by placing Scottish prisoners that they had captured in the steeple, so saving it from destruction. The town walls were finally breached by a combination of artillery and sapping. In gratitude for this defence, Charles gave Newcastle the motto 'Fortiter Defendit Triumphans' to be added to its coat of arms. The Scottish army occupied Northumberland and Durham for two years. The coal taxes had to pay for the Scottish occupation. In 1645 Charles surrendered to the Scots and was imprisoned in Newcastle for nine months. After the Civil War the coal trade on the Tyne soon picked up and exceeded its pre-war levels.
A new Guildhall was completed on the Sandhill next to the river in 1655, replacing an earlier facility damaged by fire in 1639, and became the meeting place of Newcastle Town Council. In 1681 the Hospital of the Holy Jesus was built partly on the site of the Austin Friars. The Guildhall and Holy Jesus Hospital still exist.
Charles II tried to impose a charter on Newcastle to give the king the right to appoint the mayor, sheriff, recorder and town clerk. Charles died before the charter came into effect. In 1685, James II tried to replace Corporation members with named Catholics. However, James' mandate was suspended in 1689 after the Glorious Revolution welcoming William of Orange. In 1689, after the fall of James II, the people of Newcastle tore down his bronze equestrian statue in Sandhill and tossed it into the Tyne. The bronze was later used to make bells for All Saints Church.
In 1689 the Lort Burn was covered over. At this time it was an open sewer. The channel followed by the Lort Burn became the present day Dean Street. At that time, the centre of Newcastle was still the Sandhill area, with many merchants living along the Close or on the Side. The path of the main road through Newcastle ran from the single Tyne bridge, through Sandhill to the Side, a narrow street which climbed steeply on the north-east side of the castle hill until it reached the higher ground alongside St Nicholas' Church. As Newcastle developed, the Side became lined with buildings with projecting upper stories, so that the main street through Newcastle was a narrow, congested, steep thoroughfare.
In 1701 the Keelmen's Hospital was built in the Sandgate area of the city, using funds provided by the keelmen. The building still stands today.
Eighteenth century
In the 18th century, Newcastle was the country's largest print centre after London, Oxford and Cambridge, and the Literary and Philosophical Society of 1793, with its erudite debates and large stock of books in several languages predated the London Library by half a century.
In 1715, during the Jacobite rising in favour of the Old Pretender, an army of Jacobite supporters marched on Newcastle. Many of the Northumbrian gentry joined the rebels. The citizens prepared for its arrival by arresting Jacobite supporters and accepting 700 extra recruits into the local militia. The gates of the city were closed against the rebels. This proved enough to delay an attack until reinforcements arrived forcing the rebel army to move across to the west coast. The rebels finally surrendered at Preston.
In 1745, during a second Jacobite rising in favour of the Young Pretender, a Scottish army crossed the border led by Bonnie Prince Charlie. Once again Newcastle prepared by arresting Jacobite supporters and inducting 800 volunteers into the local militia. The town walls were strengthened, most of the gates were blocked up and some 200 cannon were deployed. 20,000 regulars were billeted on the Town Moor. These preparations were enough to force the rebel army to travel south via the west coast. They were eventually defeated at Culloden in 1746.
Newcastle's actions during the 1715 rising in resisting the rebels and declaring for George I, in contrast to the rest of the region, is the most likely source of the nickname 'Geordie', applied to people from Tyneside, or more accurately Newcastle. Another theory, however, is that the name 'Geordie' came from the inventor of the Geordie lamp, George Stephenson. It was a type of safety lamp used in mining, but was not invented until 1815. Apparently the term 'German Geordie' was in common use during the 18th century.
The city's first hospital, Newcastle Infirmary opened in 1753; it was funded by public subscription. A lying-in hospital was established in Newcastle in 1760. The city's first public hospital for mentally ill patients, Wardens Close Lunatic Hospital was opened in October 1767.
In 1771 a flood swept away much of the bridge at Newcastle. The bridge had been built in 1250 and repaired after a flood in 1339. The bridge supported various houses and three towers and an old chapel. A blue stone was placed in the middle of the bridge to mark the boundary between Newcastle and the Palatinate of Durham. A temporary wooden bridge had to be built, and this remained in use until 1781, when a new stone bridge was completed. The new bridge consisted of nine arches. In 1801, because of the pressure of traffic, the bridge had to be widened.
A permanent military presence was established in the city with the completion of Fenham Barracks in 1806. The facilities at the Castle for holding assizes, which had been condemned for their inconvenience and unhealthiness, were replaced when the Moot Hall opened in August 1812.
Victorian period
Present-day Newcastle owes much of its architecture to the work of the builder Richard Grainger, aided by architects John Dobson, Thomas Oliver, John and Benjamin Green and others. In 1834 Grainger won a competition to produce a new plan for central Newcastle. He put this plan into effect using the above architects as well as architects employed in his own office. Grainger and Oliver had already built Leazes Terrace, Leazes Crescent and Leazes Place between 1829 and 1834. Grainger and Dobson had also built the Royal Arcade at the foot of Pilgrim Street between 1830 and 1832. The most ambitious project covered 12 acres 12 acres (49,000 m2) in central Newcastle, on the site of Newe House (also called Anderson Place). Grainger built three new thoroughfares, Grey Street, Grainger Street and Clayton Street with many connecting streets, as well as the Central Exchange and the Grainger Market. John Wardle and George Walker, working in Grainger's office, designed Clayton Street, Grainger Street and most of Grey Street. Dobson designed the Grainger Market and much of the east side of Grey Street. John and Benjamin Green designed the Theatre Royal at the top of Grey Street, where Grainger placed the column of Grey's Monument as a focus for the whole scheme. Grey Street is considered to be one of the finest streets in the country, with its elegant curve. Unfortunately most of old Eldon Square was demolished in the 1960s in the name of progress. The Royal Arcade met a similar fate.
In 1849 a new bridge was built across the river at Newcastle. This was the High Level Bridge, designed by Robert Stephenson, and slightly up river from the existing bridge. The bridge was designed to carry road and rail traffic across the Tyne Gorge on two decks with rail traffic on the upper deck and road traffic on the lower. The new bridge meant that traffic could pass through Newcastle without having to negotiate the steep, narrow Side, as had been necessary for centuries. The bridge was opened by Queen Victoria, who one year later opened the new Central Station, designed by John Dobson. Trains were now able to cross the river, directly into the centre of Newcastle and carry on up to Scotland. The Army Riding School was also completed in 1849.
In 1854 a large fire started on the Gateshead quayside and an explosion caused it to spread across the river to the Newcastle quayside. A huge conflagration amongst the narrow alleys, or 'chares', destroyed the homes of 800 families as well as many business premises. The narrow alleys that had been destroyed were replaced by streets containing blocks of modern offices.
In 1863 the Town Hall in St Nicholas Square replaced the Guildhall as the meeting place of Newcastle Town Council.
In 1876 the low level bridge was replaced by a new bridge known as the Swing Bridge, so called because the bridge was able to swing horizontally on a central axis and allow ships to pass on either side. This meant that for the first time sizeable ships could pass up-river beyond Newcastle. The bridge was built and paid for by William Armstrong, a local arms manufacturer, who needed to have warships access his Elswick arms factory to fit armaments to them. The Swing Bridge's rotating mechanism is adapted from the cannon mounts developed in Armstrong's arms works. In 1882 the Elswick works began to build ships as well as to arm them. The Barrack Road drill hall was completed in 1890.
Industrialisation
In the 19th century, shipbuilding and heavy engineering were central to the city's prosperity; and the city was a powerhouse of the Industrial Revolution. Newcastle's development as a major city owed most to its central role in the production and export of coal. The phrase "taking coals to Newcastle" was first recorded in 1538; it proverbially denotes bringing a particular commodity to a place that has more than enough of it already.
Innovation in Newcastle and surrounding areas included the following:
George Stephenson developed a miner's safety lamp at the same time that Humphry Davy developed a rival design. The lamp made possible the opening up of ever deeper mines to provide the coal that powered the industrial revolution.
George and his son Robert Stephenson were hugely influential figures in the development of the early railways. George developed Blücher, a locomotive working at Killingworth colliery in 1814, whilst Robert was instrumental in the design of Rocket, a revolutionary design that was the forerunner of modern locomotives. Both men were involved in planning and building railway lines, all over this country and abroad.
Joseph Swan demonstrated a working electric light bulb about a year before Thomas Edison did the same in the USA. This led to a dispute as to who had actually invented the light bulb. Eventually the two rivals agreed to form a mutual company between them, the Edison and Swan Electric Light Company, known as Ediswan.
Charles Algernon Parsons invented the steam turbine, for marine use and for power generation. He used Turbinia, a small, turbine-powered ship, to demonstrate the speed that a steam turbine could generate. Turbinia literally ran rings around the British Fleet at a review at Spithead in 1897.
William Armstrong invented a hydraulic crane that was installed in dockyards up and down the country. He then began to design light, accurate field guns for the British army. These were a vast improvement on the existing guns that were then in use.
The following major industries developed in Newcastle or its surrounding area:
Glassmaking
A small glass industry existed in Newcastle from the mid-15th century. In 1615 restrictions were put on the use of wood for manufacturing glass. It was found that glass could be manufactured using the local coal, and so a glassmaking industry grew up on Tyneside. Huguenot glassmakers came over from France as refugees from persecution and set up glasshouses in the Skinnerburn area of Newcastle. Eventually, glass production moved to the Ouseburn area of Newcastle. In 1684 the Dagnia family, Sephardic Jewish emigrants from Altare, arrived in Newcastle from Stourbridge and established glasshouses along the Close, to manufacture high quality flint glass. The glass manufacturers used sand ballast from the boats arriving in the river as the main raw material. The glassware was then exported in collier brigs. The period from 1730 to 1785 was the highpoint of Newcastle glass manufacture, when the local glassmakers produced the 'Newcastle Light Baluster'. The glassmaking industry still exists in the west end of the city with local Artist and Glassmaker Jane Charles carrying on over four hundred years of hot glass blowing in Newcastle upon Tyne.
Locomotive manufacture
In 1823 George Stephenson and his son Robert established the world's first locomotive factory near Forth Street in Newcastle. Here they built locomotives for the Stockton and Darlington Railway and the Liverpool and Manchester Railway, as well as many others. It was here that the famous locomotive Rocket was designed and manufactured in preparation for the Rainhill Trials. Apart from building locomotives for the British market, the Newcastle works also produced locomotives for Europe and America. The Forth Street works continued to build locomotives until 1960.
Shipbuilding
In 1296 a wooden, 135 ft (41 m) long galley was constructed at the mouth of the Lort Burn in Newcastle, as part of a twenty-ship order from the king. The ship cost £205, and is the earliest record of shipbuilding in Newcastle. However the rise of the Tyne as a shipbuilding area was due to the need for collier brigs for the coal export trade. These wooden sailing ships were usually built locally, establishing local expertise in building ships. As ships changed from wood to steel, and from sail to steam, the local shipbuilding industry changed to build the new ships. Although shipbuilding was carried out up and down both sides of the river, the two main areas for building ships in Newcastle were Elswick, to the west, and Walker, to the east. By 1800 Tyneside was the third largest producer of ships in Britain. Unfortunately, after the Second World War, lack of modernisation and competition from abroad gradually caused the local industry to decline and die.
Armaments
In 1847 William Armstrong established a huge factory in Elswick, west of Newcastle. This was initially used to produce hydraulic cranes but subsequently began also to produce guns for both the army and the navy. After the Swing Bridge was built in 1876 allowing ships to pass up river, warships could have their armaments fitted alongside the Elswick works. Armstrong's company took over its industrial rival, Joseph Whitworth of Manchester in 1897.
Steam turbines
Charles Algernon Parsons invented the steam turbine and, in 1889, founded his own company C. A. Parsons and Company in Heaton, Newcastle to make steam turbines. Shortly after this, he realised that steam turbines could be used to propel ships and, in 1897, he founded a second company, Parsons Marine Steam Turbine Company in Wallsend. It is there that he designed and manufactured Turbinia. Parsons turbines were initially used in warships but soon came to be used in merchant and passenger vessels, including the liner Mauretania which held the blue riband for the Atlantic crossing until 1929. Parsons' company in Heaton began to make turbo-generators for power stations and supplied power stations all over the world. The Heaton works, reduced in size, remains as part of the Siemens AG industrial giant.
Pottery
In 1762 the Maling pottery was founded in Sunderland by French Huguenots, but transferred to Newcastle in 1817. A factory was built in the Ouseburn area of the city. The factory was rebuilt twice, finally occupying a 14-acre (57,000 m2) site that was claimed to be the biggest pottery in the world and which had its own railway station. The pottery pioneered use of machines in making potteries as opposed to hand production. In the 1890s the company went up-market and employed in-house designers. The period up to the Second World War was the most profitable with a constant stream of new designs being introduced. However, after the war, production gradually declined and the company closed in 1963.
Expansion of the city
Newcastle was one of the boroughs reformed by the Municipal Corporations Act 1835: the reformed municipal borough included the parishes of Byker, Elswick, Heaton, Jesmond, Newcastle All Saints, Newcastle St Andrew, Newcastle St John, Newcastle St Nicholas, and Westgate. The urban districts of Benwell and Fenham and Walker were added in 1904. In 1935, Newcastle gained Kenton and parts of the parishes of West Brunton, East Denton, Fawdon, Longbenton. The most recent expansion in Newcastle's boundaries took place under the Local Government Act 1972 on 1 April 1974, when Newcastle became a metropolitan borough, also including the urban districts of Gosforth and Newburn, and the parishes of Brunswick, Dinnington, Hazlerigg, North Gosforth and Woolsington from the Castle Ward Rural District, and the village of Westerhope.
Meanwhile Northumberland County Council was formed under the Local Government Act 1888 and benefited from a dedicated meeting place when County Hall was completed in the Castle Garth area of Newcastle in 1910. Following the Local Government Act 1972 County Hall relocated to Morpeth in April 1981.
Twentieth century
In 1925 work began on a new high-level road bridge to span the Tyne Gorge between Newcastle and Gateshead. The capacity of the existing High-Level Bridge and Swing Bridge were being strained to the limit, and an additional bridge had been discussed for a long time. The contract was awarded to the Dorman Long Company and the bridge was finally opened by King George V in 1928. The road deck was 84 feet (26 m) above the river and was supported by a 531 feet (162 m) steel arch. The new Tyne Bridge quickly became a symbol for Newcastle and Tyneside, and remains so today.
During the Second World War, Newcastle was largely spared the horrors inflicted upon other British cities bombed during the Blitz. Although the armaments factories and shipyards along the River Tyne were targeted by the Luftwaffe, they largely escaped unscathed. Manors goods yard and railway terminal, to the east of the city centre, and the suburbs of Jesmond and Heaton suffered bombing during 1941. There were 141 deaths and 587 injuries, a relatively small figure compared to the casualties in other industrial centres of Britain.
In 1963 the city gained its own university, the University of Newcastle upon Tyne, by act of parliament. A School of Medicine and Surgery had been established in Newcastle in 1834. This eventually developed into a college of medicine attached to Durham University. A college of physical science was also founded and became Armstrong College in 1904. In 1934 the two colleges merged to become King's College, Durham. This remained as part of Durham University until the new university was created in 1963. In 1992 the city gained its second university when Newcastle Polytechnic was granted university status as Northumbria University.
Newcastle City Council moved to the new Newcastle Civic Centre in 1968.
As heavy industries declined in the second half of the 20th century, large sections of the city centre were demolished along with many areas of slum housing. The leading political figure in the city during the 1960s was T. Dan Smith who oversaw a massive building programme of highrise housing estates and authorised the demolition of a quarter of the Georgian Grainger Town to make way for Eldon Square Shopping Centre. Smith's control in Newcastle collapsed when it was exposed that he had used public contracts to advantage himself and his business associates and for a time Newcastle became a byword for civic corruption as depicted in the films Get Carter and Stormy Monday and in the television series Our Friends in the North. However, much of the historic Grainger Town area survived and was, for the most part, fully restored in the late 1990s. Northumberland Street, initially the A1, was gradually closed to traffic from the 1970s and completely pedestrianised by 1998.
In 1978 a new rapid transport system, the Metro, was built, linking the Tyneside area. The system opened in August 1980. A new bridge was built to carry the Metro across the river between Gateshead and Newcastle. This was the Queen Elizabeth II Bridge, commonly known as the Metro Bridge. Eventually the Metro system was extended to reach Newcastle Airport in 1991, and in 2002 the Metro system was extended to the nearby city of Sunderland.
As the 20th century progressed, trade on the Newcastle and Gateshead quaysides gradually declined, until by the 1980s both sides of the river were looking rather derelict. Shipping company offices had closed along with offices of firms related to shipping. There were also derelict warehouses lining the riverbank. Local government produced a master plan to re-develop the Newcastle quayside and this was begun in the 1990s. New offices, restaurants, bars and residential accommodation were built and the area has changed in the space of a few years into a vibrant area, partially returning the focus of Newcastle to the riverside, where it was in medieval times.
The Gateshead Millennium Bridge, a foot and cycle bridge, 26 feet (7.9 m) wide and 413 feet (126 m) long, was completed in 2001. The road deck is in the form of a curve and is supported by a steel arch. To allow ships to pass, the whole structure, both arch and road-deck, rotates on huge bearings at either end so that the road deck is lifted. The bridge can be said to open and shut like a human eye. It is an important addition to the re-developed quayside area, providing a vital link between the Newcastle and Gateshead quaysides.
Recent developments
Today the city is a vibrant centre for office and retail employment, but just a short distance away there are impoverished inner-city housing estates, in areas originally built to provide affordable housing for employees of the shipyards and other heavy industries that lined the River Tyne. In the 2010s Newcastle City Council began implementing plans to regenerate these depressed areas, such as those along the Ouseburn Valley.
Lunar eclipses present an excellent opportunity to learn how to observe the atmospheres of those exoplanets in stellar systems that are appropriately and fortuitously oriented in space. The geometric configuration of the three bodies involved is similar when both produce a visible transit of a planet across the face of a star.
As seen from the Moon during a total lunar eclipse, the Earth passes in front of the Sun and almost completely shadows the face of the Moon from direct sunlight whilst it remains in umbral shadow. However, because the Earth has an atmosphere, some of the sunlight that grazes the limb is refracted and scattered towards the hidden Moon to paint it a deep, blood-red hue.
In regions free from cloud and high mountains, these grazing sunbeams will travel along a path containing up to about eighty times as much atmosphere as you would look through when observing a star at the zenith from sea level. This very long path, twice as long as a sunset or sunrise, imprints a strong signature of the atmospheric composition of the Earth on the light that reaches the Moon. By capturing this dim lunar light with a telescope and a spectrograph on or near the Earth we can interpret this signature to compile a detailed picture our own atmosphere.
While an exoplanet transit will not provide an umbral shadow that is accessible to us, it can place us in its penumbra. Teasing the signature of the exoplanet's atmosphere from a signal that is almost completely dominated by the unshadowed starlight requires a great deal of care and a large telescope. But it can, and has now quite often, been done. Although we do not yet have the telescopes to achieve this for exoplanets as small as Earth, several are now (2021) being constructed or planned.
This plot of the spectrum of a low Sun and two lunar eclipses is presented to show what the results look like and what they show.
Each of them reveal what is essentially the transmission of the Earth's atmosphere. This is calculated by taking the ratio of the transmitted light to the source which is, of course, the Sun. By taking this ratio, we remove all the spectral features arising at the Sun, leaving only those formed by the Earth's atmospheric absorption and scattering: we call these the 'telluric' lines and bands.
The top (blue line) spectrum is from the low Sun (altitude 8.4°) observed in Munich in August 2011. The visible part was obtained with a JAZ spectrometer while the infrared (from ~950nm) is from a NirQuest, both from Ocean Optics. In this case the ratio was taken with observations earlier in the day with a solar altitude of 51°.
The bottom (red line) spectrum, kindly supplied by Enric Pallé, is from the Moon in the Earth's umbral shadow taken from La Palma during the lunar eclipse of 16 August 2008. This was obtained by visible and infrared spectrographs on different telescopes. Full descriptions can be found in the Nature paper by Pallé et al. (Vol 459|11 June 2009|doi:10.1038/nature08050) along with supplementary information. See:
The central (green line) spectrum shows a low resolution representation of a considerably higher resolution spectrum extending up to 1000nm observed from China during the 10 December 2011 lunar eclipse. The detailed analysis of these observations is presented in the paper by Yan et al. (International Journal of Astrobiology 14 (2): 255–266, 2015). See:
Both of the eclipse spectra show the ratio of the measurements of the lunar surface during the umbral part of the eclipse to that of the same part of the bright Moon out of eclipse taken at closely adjacent times. This procedure removes not only the solar spectral features but also those resulting from the lunar surface itself and from the atmospheric path between the Moon and the telescope, leaving a clean measurement of the long grazing (tangential) path taken by the sunlight reaching the Moon past the Earth.
The infrared part of the spectrum, above 1000nm, is dominated by overtones of the fundamental water vapour bands associated with the stretching a bending of the water molecule (en.wikipedia.org/wiki/Electromagnetic_absorption_by_water). In addition to some carbon dioxide and methane absorptions, there are two important and interesting features associated with collisions between two oxygens and, in one case, between oxygen and nitrogen molecules. These are called Collision Induced Absorptions (CIA) which, because they require the close proximity of two molecules, have a strength which depends on the square of atmospheric density and so become especially strong when sunlight takes a path through the low atmosphere. In the plots, some of the stronger CIA bands are marked in pale green. The oxygen-oxygen collisions are labelled O_4. A modern quantum mechanical description of the formation of these bands can be found at: www.theochem.ru.nl/files/theses/karman-phdthesis-2018.pdf
Note the great strength of the O_4 + N_2•N_2 band in the umbral spectrum of the 2008 eclipse (red line) when almost all of the sunlight reaching the Moon has travelled though the low atmosphere.
The visible spectrum is marked by strong scattering (Rayleigh and aerosol) extinction and by very intense ozone (Chappuis band) absorption, the combination of which provides the colour palette of a lunar eclipse ranging from deep red-orange to ultramarine blue.
Of interest in the 2011 eclipse spectrum (green line) is the weakness of the water absorption spectrum. The tangent path of the sunlight reaching the Moon in this umbral spectrum passed over the coast of Antarctica south of Australia. Here the very low temperatures freeze out the water to give an extraordinarily dry atmosphere.
More details of the interpretations of the eclipse spectra can be found in the papers referred to above and also in an article entitled "How the Sun Paints the Sky" which can be found on the Herschel Society website at:

+++ DISCLAIMER +++
Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!
After the Saab 38 (also known as B3LA) had been cancelled in 1979 in favor of the more advanced Saab JAS 39 Gripen multi-role fighter, Saab presented in 1991 a new trainer design to the Swedish Air Force as a replacement for the Saab 105 (Sk 60) transitional trainer, light attack and reconnaissance aircraft. This new aircraft was internally called "FSK900". The aircraft was a conservative design, with such a configurational resemblance to the Dassault-Dornier Alpha Jet that it is hard to believe Saab engineers didn't see the Alpha Jet as a model for what they wanted to do. However, even if that was the case, the FSK900 was by no means a copy of the Alpha Jet, and the two machines could be easily told apart at a glance. FSK900 had a muscular, rather massive appearance, while the Alpha Jet was more wasp-like and very sleek. The FSK900 was also bigger in length and span and had an empty weight about 10% greater.
The FSK900 was mostly made of aircraft aluminum alloys, with some control surfaces made of carbon-fiber / epoxy composite, plus very selective use of titanium. It had high-mounted swept wings, with a supercritical airfoil section and a leading-edge dogtooth; a conventional swept tail assembly; tricycle landing gear; twin engines, one mounted in a pod along each side of the fuselage; and a tandem-seat cockpit with dual controls.
The wings had a sweep of 27.5°, an anhedral droop of 7°, and featured ailerons for roll control as well as double slotted flaps. The tailplanes were all-moving, and also featured an anhedral of 7°. An airbrake was mounted on each side of the rear fuselage. Flight controls were hydraulic, and hydraulic systems were dual redundant.
Instructor and cadet sat in tandem in a common cockpit, both on zero-zero ejection seats, with the instructor's seat in the rear raised 27 centimeters (10.6 inches) to give a good forward view. The cockpit was pressurized and featured a one-piece canopy, hinged open to the right, which provided excellent visibility.
The landing gear assemblies all featured single wheels, with the nose gear retracting forward and the main gear retracting forward and into the fuselage, featuring an antiskid braking system. The twin engines were two Williams International FJ44-4M turbofans without reheat, each rated at 16.89 kN (3,790 lbst). These were the same engines that Saab had also proposed for Saab’s Sk 60 modernization program, even though a less powerful variant for the lighter aircraft.
The FSK900 could be fitted with two pylons under each wing and under the fuselage centerline, for a total of five hardpoints and a total external payload of 2,500 kg (5,500 lb). The inner wing pylons were wet and could take 450 liter (119 US gallon) auxiliary tanks. External stores included a centerline target winch for the target tug role, an air-sampling pod for detection of fallout or other atmospheric pollutants, jammer or chaff pods for electronic warfare training, a camera/sensor pod and a baggage pod for use in the liaison role. The aircraft also featured a baggage compartment in the center fuselage, which also offered space for other special equipment or future updates.
Potential armament comprised a conformal ventral pod with a single 27 mm Mauser BK-27 revolver cannon with 120 rounds (the same weapon that eventually went into the Saab Gripen). Other weapons included various iron and cluster bombs of up to 454 kg (1.000 lb) caliber, unguided missiles of various calibers and the Rb.74 (AIM-9L Sidewinder) AAM. A radar was not mounted, but the FSK900’s nose section offered enough space for a radome.
The Swedish Air Force accepted the Saab design, leading to a contract for two nonflying static-test airframes and four flying prototypes. Detail design was complete by the end of 1993 and prototype construction began in the spring of 1994, leading to first flight of the initial prototype on 29 July 1994. The first production "Sk 90A", how the basic trainer type was officially dubbed, was delivered to the Swedish Air Force in 1996.
A total of 108 production Sk 90s were built until 1999 in several versions. The initial Sk 90A trainer was the basis for the Sk 90B variant, which carried a weather radar (this variant was not adopted by the Swedish air force but sold to Austria) and the C variant with a set of cameras in the nose for the Swedish air force. In service, the type was regarded as strong, agile, and pleasant to fly, while being cheap to operate. Swedish Sk 90As flying in the training role were typically painted in the unique “Fields & Meadows” splinter camouflage, although decorative paint jobs showed up on occasion and many aircraft received additional dayglow markings. Some of the few aircraft given to operational squadrons, which used them for keeping up flight hours and as hacks, had been painted in an all-grey camouflage to match the combat aircraft they shared the flight line with.
Despite its qualities and potential, the Sk 90 did not attain much foreign interest, primarily suffering from bad timing and from the focus on domestic demands. The aircraft came effectively 10 years too late to become a serious export success, and in the end the Sk 90 was very similar to the Dassault/Dornier Alpha Jet (even though it was cheaper to operate) - at a time when the German Luftwaffe started to prematurely phase out its attack variant and flooded the global´market with cheap second hand aircraft in excellent condition. Furthermore, the Saab Sk 90 had, with the BAe Hawk, another proven competitor with a long operational track record all over the world.
Potential buyers were Malaysia as well as Singapore, Myanmar, Finland, Poland and Hungary. Austria eventually procured 36 Sk 90 Ö in 2002, replacing its Saab 105 fleet and keeping up its close connection with Saab since the Seventies, and a late customer became the independent Republic of Scotland in 2017, initially with a dozen leased Saab Sk 90A trainers.
This procurement was preceded by a White Paper published by the Scottish National Party (SNP) in 2013, which stated that an independent Scotland would have an air force equipped with up to 16 air defense aircraft, six tactical transports, utility rotorcraft and maritime patrol aircraft, and be capable of “contributing excellent conventional capabilities” to NATO. Outlining its ambition to establish an air force with an eventual 2,000 uniformed personnel and 300 reservists, the SNP stated the organization would initially be equipped with “a minimum of 12 interceptors in the Eurofighter/Typhoon class, based at Lossiemouth, a tactical air transport squadron, including around six Lockheed Martin C-130J Hercules, and a helicopter squadron”.
According to the document, “Key elements of air forces in place at independence, equipped initially from a negotiated share of current UK assets, will secure core tasks, principally the ability to police Scotland’s airspace, within NATO.” An in-country air command and control capability would be established within five years of a decision in favor of independence, it continues, with staff also to be “embedded within NATO structures”.
This plan was immediately set into action after the country's independence from Great Britain in late 2017 with the purchase of twelve refurbished Saab JAS 39A Gripen interceptors for Quick Reaction Alert duties and former Swedish Air Force Sk 90A trainers for the nascent Republic of Scotland Air Corps (RoScAC), locally called Saab Sk90A “Iolaire” (Eaglet) T.1. These machines either came from operational Swedish squadrons or were put back into operation from mothballed overstock.
All machines were delivered to Scotland in the Swedish all-grey paint scheme, the machines taken from operational service had their original Swedish markings just painted over. The were all exclusively allocated to the newly established Eaglais a' Bhaile Ùir Flying Training School at Kirknewtoun (a former RAF air base) near Edinburgh. In 2019, the RoScAC’s first brand new aircraft arrived in the form of TF-50 “Golden Eagle” fighters from South Korea, which, as multi-role two seaters, complemented the Saab Sk 90’s in the advanced trainer role and also took over air space patrol duties from the Scottish JAS 39.
In early 2020, the leasing contract for the Sk 90s with Sweden was changed into a formal purchase, and the Iolaire fleet (as well as the Gripen fighters) gradually received the RoScAC’s new camouflage scheme in grey and green, which had been introduced with the TF-50s.

The kit and its assembly:
This whif is a rarity among my builds, since it is an alternative reality model. A fictional air force of an independent Scotland crept into my mind after the hysterical “Brexit” events in 2016 and the former (failed) public vote concerning the independence of Scotland from the UK. However, the situation bore some serious storytelling potential: What would happen to the military if the independence would have actually taken place and British forces had left the country?
The aforementioned Scottish National Party (SNP) paper from 2013 is actually real, and I took it as a guideline. Primary focus would certainly be set on air space defense, and the Gripen appeared as a good and not too expensive choice. An advanced trainer would also have been needed, and the Sk 90 (a personal invention and already built as a Swedish and Austrian aircraft) would fulfill a complementary role.
A Scottish Sk 90 had been on my agenda since 2016, and now materialized as an addition to my Scottish TF-50 and two Sk 90s (a swedish and an Austrian one). The Saab Sk 90 is basically the 1:72 Kawasaki T-4 from Hasegawa, and since it was to depict an original Sk 90A, formerly operated by Sweden, it was built without modifications. The kit is relatively simple and fit is quite good, even though some PSR was necessary on almost any seam – there are actually two T-4 molds, and this one is the more recent offering.
Painting and markings:
I wanted to depict a RoScAC aircraft of the first hour, so I went for a Swedish look with tactical markings from the new operator. Since I already had a Sk 90 in Swedish “Fields & Meadows” camouflage, I decided to go for a Gripen-esque grey-in-grey livery.
Swedish JAS 39 carry a two-tone livery; the upper tone is called pansargrå (tank grey, which is, according to trustworthy sources, very close to FS 36173, Neutral Grey), while the undersides are painted in duvagrå (dove grey, FS 36373, a tone with the confusing name ”High Low Visibility Light Grey”), and the simple pattern was faithfully adapted to the T-4.
After checking a lot of Gripen pictures I selected different tones, though, because the colors appear much lighter in real life. I ended up with FS 36231 (Dark Gull Grey, Testors 1740) and RLM 63 (Lichtgrau, Testors 2077) – in combination, these tones come IMHO quite close to the real thing?
After a light black ink wash I emphasized single panels with Humbrol 165 and 147. The cockpit interior was painted with Revell 47 (Mausgrau) while the landing gear became glossy white.
For the RoScAC look I added some manually overpainted patches where the former Swedish roundels and tactical markings would have been. As a trainer, I also added orange dayglow markings on the fin and the wings, created with generic decal sheet material (TL Modellbau). The de-icing devices on the wings’ and fin’s leading edges were created with black decal stripes instead of paint, a very tidy and simple method. Decal strips in silver were used on the fin’s rudder and on the flaps. Small things, but they grade the grey model up visually.
Another creative field were the national markings: how could fictional Scottish roundels look like, and how to create them so that they are easy to make and replicate (for a full set for this kit, as well as for potential future builds…)? Designing and printing marking decals myself was an option, but I eventually settled for a composite solution which somewhat influenced the roundels’ design, too.
My Scottish roundel interpretation, already used on my RoScAC T-50, consists of a simple blue disk with a white cross – a straightforward solution since it’s different from any other contemporary national marking, esp. the UK roundel, and easy to create from single decal parts. In fact, the roundel discs were die-punched from blue decal sheet, and the cross consists of two thin white decal strips, cut into the correct length with the same stencil, again using generic sheet material from TL Modellbau.
Another issue was the potential tactical code, and a small fleet only needs a simple system. Going back to a WWII system with letter codes for squadrons and individual aircraft was one option, but, IMHO, still too complicated. However, for individual aircraft identification I adopted the familiar British single letter aircraft code, and since the RoScAC would certainly not operate too many squadrons, I rather adapted a system similar to the Swedish or Spanish format with a single number representing the squadron – or, in this case a letter, because the fictional Flying Training School would not be a front line unit.
The result is a simple 2-digit code, and I adapted the German system of placing the tactical code on the fuselage, separated by the roundel. Keeping British traditions up I repeated the individual aircraft code letter on the fin, where I also placed a Scottish flag (scratched from the same decal material as the roundels. A small serial number, created from single black letters (once more Tl Modellbau material) was added on the rear fuselage, and, for some local pride, I added a self-printed coat-of-arms of Edinburgh to the air intakes.
Finally, after some light weathering, the kit was finally sealed with matt acrylic varnish (Italeri).
Creating this whif, based on an alternative historic timeline and with a near future perspective, was fun – and it might spawn more models that circle around this story. A certain future build is a Saab Gripen in RoScAC colors and there might also be an entry level trainer (Shorts Tucano?), some helicopters for the army or SAR duties and maybe a transport aircraft, but not a big one. The foundation has been laid out, now it’s time to fill Scotland’s alternative recent history with detail and hardware proof. ;-)

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!
After the Saab 38 (also known as B3LA) had been cancelled in 1979 in favor of the more advanced Saab JAS 39 Gripen multi-role fighter, Saab presented in 1991 a new trainer design to the Swedish Air Force as a replacement for the Saab 105 (Sk 60) transitional trainer, light attack and reconnaissance aircraft. This new aircraft was internally called "FSK900". The aircraft was a conservative design, with such a configurational resemblance to the Dassault-Dornier Alpha Jet that it is hard to believe Saab engineers didn't see the Alpha Jet as a model for what they wanted to do. However, even if that was the case, the FSK900 was by no means a copy of the Alpha Jet, and the two machines could be easily told apart at a glance. FSK900 had a muscular, rather massive appearance, while the Alpha Jet was more wasp-like and very sleek. The FSK900 was also bigger in length and span and had an empty weight about 10% greater.
The FSK900 was mostly made of aircraft aluminum alloys, with some control surfaces made of carbon-fiber / epoxy composite, plus very selective use of titanium. It had high-mounted swept wings, with a supercritical airfoil section and a leading-edge dogtooth; a conventional swept tail assembly; tricycle landing gear; twin engines, one mounted in a pod along each side of the fuselage; and a tandem-seat cockpit with dual controls.
The wings had a sweep of 27.5°, an anhedral droop of 7°, and featured ailerons for roll control as well as double slotted flaps. The tailplanes were all-moving, and also featured an anhedral of 7°. An airbrake was mounted on each side of the rear fuselage. Flight controls were hydraulic, and hydraulic systems were dual redundant.
Instructor and cadet sat in tandem in a common cockpit, both on zero-zero ejection seats, with the instructor's seat in the rear raised 27 centimeters (10.6 inches) to give a good forward view. The cockpit was pressurized and featured a one-piece canopy, hinged open to the right, which provided excellent visibility.

Krafla Geothermal Power Plant, in north Iceland, near Myvatn. Interesting pipe configuration to drive through the power plant
The Citroën DS (French pronunciation: [si.tʁɔ.ˈɛn de ɛs]) is a front-engine, front-wheel-drive executive car manufactured and marketed by the French company Citroën from 1955 to 1975 in sedan, wagon/estate and convertible body configurations. Italian sculptor and industrial designer Flaminio Bertoni and the French aeronautical engineer André Lefèbvre styled and engineered the car. Paul Magès developed the hydropneumatic self-levelling suspension.
Noted for its aerodynamic, futuristic body design and innovative technology, the DS set new standards in ride quality, handling, and braking—and was the first production car equipped with disc brakes.
Citroën sold 1,455,746 examples, including 1,330,755 built at the manufacturer's Paris Quai André-Citroën production plant.
The DS came third in the 1999 Car of the Century poll recognizing the world's most influential auto designs and was named the most beautiful car of all time by Classic & Sports Car magazine
MODEL HISTORY
After 18 years of secret development as the successor to the Traction Avant, the DS 19 was introduced on 5 October 1955 at the Paris Motor Show. In the first 15 minutes of the show, 743 orders were taken, and orders for the first day totalled 12,000. During the 10 days of the show, the DS took in 80,000 deposits; a record that has stood for over 60 years.
Contemporary journalists said the DS pushed the envelope in the ride vs. handling compromise possible in a motor vehicle.
To a France still deep in reconstruction after the devastation of World War II, and also building its identity in the post-colonial world, the DS was a symbol of French ingenuity. The DS was distributed to many territories throughout the world.
It also posited the nation's relevance in the Space Age, during the global race for technology of the Cold War. Structuralist philosopher Roland Barthes, in an essay about the car, said that it looked as if it had "fallen from the sky". An American advertisement summarised this selling point: "It takes a special person to drive a special car".
Because they were owned by the technologically aggressive tire manufacturer Michelin, Citroën had designed their cars around the technically superior radial tire since 1948, and the DS was no exception.
The car featured a novel hydropneumatic suspension including an automatic leveling system and variable ground clearance, developed in-house by Paul Magès. This suspension allowed the DS to travel quickly on the poor road surfaces common in France.
In addition, the vehicle had power steering and a semi-automatic transmission (the transmission required no clutch pedal, but gears still had to be shifted by hand), though the shift lever controlled a powered hydraulic shift mechanism in place of a mechanical linkage, and a fibreglass roof which lowered the centre of gravity and so reduced weight transfer. Inboard front brakes (as well as independent suspension) reduced unsprung weight. Different front and rear track widths and tyre sizes reduced the unequal tyre loading, which is well known to promote understeer, typical of front-engined and front-wheel drive cars.
As with all French cars, the DS design was affected by the tax horsepower system, which effectively mandated very small engines. Unlike the Traction Avant predecessor, there was no top-of-range model with a powerful six-cylinder engine. Citroën had planned an air-cooled flat-6 engine for the car, but did not have the funds to put the prototype engine into production.
The DS placed third in the 1999 Car of the Century competition, and fifth on Automobile Magazine's "100 Coolest Cars" listing in 2005. It was also named the most beautiful car of all time by Classic & Sports Car magazine after a poll of 20 world-renowned car designers, including Giorgetto Giugiaro, Ian Callum, Roy Axe, Paul Bracq, and Leonardo Fioravanti.
NAME
Both the DS and its simpler sibling, the ID, used a punning name. "DS" is pronounced in French as "Déesse" (goddess); "ID" is pronounced as "Idée" (idea). An intermediate model was called the DW.
MOTORSPORT
The DS was successful in motorsports like rallying, where sustained speeds on poor surfaces are paramount, and won the Monte Carlo Rally in 1959. In the 1000 Lakes Rally, Pauli Toivonen drove a DS19 to victory in 1962.
In 1966, the DS won the Monte Carlo Rally again, with some controversy as the competitive BMC Mini-Cooper team was disqualified due to rule infractions. Ironically, Mini was involved with DS competition again two years later, when a drunk driver in a Mini in Sydney Australia crashed into the DS that was leading the 1968 London–Sydney Marathon, 98 miles from the finish line. The DS was still competitive in the grueling 1974 London-Sahara-Munich World Cup Rally, where it won over 70 other cars, only 5 of which even completed the entire event.
TECHNICAL INNOVATION - HYDRAULIC SYSTEMS
In conventional cars, hydraulics are only used in brakes and power steering. In the DS they were also used for the suspension, clutch and transmission. The cheaper 1957 ID19 did have manual steering and a simplified power-braking system. An engine driven pump pressurizes the closed system to 2,400 pounds per square inch.
At a time when few passenger vehicles had independent suspension on all wheels, the application of the hydraulic system to the car's suspension system to provide a self-levelling system was an innovative move. This suspension allowed the car to achieve sharp handling combined with very high ride quality, frequently compared to a "magic carpet".
The hydropneumatic suspension used was pioneered the year before, on the rear of another car from Citroën, the top of range Traction Avant 15CV-H.
IMPACT ON CITROEN BRAND DEVELOPMENT
The 1955 DS cemented the Citroën brand name as an automotive innovator, building on the success of the Traction Avant, which had been the world's first mass-produced unitary body front-wheel-drive car in 1934. In fact, the DS caused such a huge sensation that Citroën was apprehensive that future models would not be of the same bold standard. No clean sheet new models were introduced from 1955 to 1970.
The DS was a large, expensive executive car and a downward brand extension was attempted, but without result. Throughout the late 1950s and 1960s Citroën developed many new vehicles for the very large, profitable market segments between the 2CV and the DS, occupied by vehicles like the Peugeot 403, Renault 16 and Ford Cortina, but none made it into production. Either they had uneconomic build costs, or were ordinary "me too" cars, not up to the company's high standard of innovation. As Citroën was owned by Michelin from 1934 to 1974 as a sort of research laboratory, such broad experimentation was possible. Michelin after all was getting a powerful advertisement for the capabilities of the radial tire Michelin had invented, when such experimentation was successful.
New models based on the small, utilitarian 2CV economy car were introduced, notably the 1961 Ami. It was also designed by Flaminio Bertoni and aimed to combine Three-box styling with the chassis of the 2CV. The Ami was very successful in France, but less so on export markets. Many found the styling controversial, and the car noisy and underpowered. The Dyane, was a modernised 2CV with a hatchback, competed with the 2CV inspired Renault 4 Hatchback. All these 2 cylinder models were very small, so there remained a wide market gap to the DS range all through the 1960s.
In 1970, Citroën finally introduced a car to target the mid-range - the Citroën GS, which won the "European car of the Year" for 1971 and sold 2.5 million units. It combined a small 55 horsepower flat-4 air-cooled engine with Hydropneumatic suspension. The intended 106 horsepower Wankel rotary-engined version with more power did not reach full production.
REPLACING THE DS
The DS remained popular and competitive throughout its production run. Its peak production year was 1970. Certain design elements like the somewhat narrow cabin, column-mounted gearstick, and separate fenders began to seem a little old-fashioned in the 1970s.
Citroën invested enormous resources to design and launch an entirely new vehicle in 1970, the SM, which was in effect a thoroughly modernized DS, with similar length, but greater width. The manual gearbox was a modified DS unit. The front disc brakes were the same design. Axles, wheel bearings, steering knuckles, and hydraulic components were either DS parts or modified DS parts.
The SM had a different purpose than replacing the 15-year-old DS design however - it was meant to launch Citroën into a completely new luxury grand touring market segment. Only fitted with a costly, exotic Maserati engine, the SM was faster and much more expensive than the DS. The SM was not designed to be a practical 4-door saloon suitable as a large family car, the key market for vehicles of this type in Europe. Typically, manufacturers would introduce low-volume coupés based on parts shared with an existing saloon, not as unique models, a contemporary example being the Mercedes-Benz SLC-Class.
The SM's high price and limited utility of the 2+2 seating configuration, meant the SM as actually produced could not seize the mantle from the DS.
So, while the design funds invested would allow the DS to be replaced by two cars - a 'modern DS' and the smaller CX, it was left to the CX alone to provide Citroën's large family or executive car in the model range.
The last DS came off the production line on 24 April 1975 - the manufacturer had taken the elementary precaution of building up approximately eight-month's of inventory of the "break" (estate/station wagon) version of the DS, to cover the period till Autumn 1975 when the estate/station wagon version of the CX would be introduced.
DEVELOPMENT
The DS always maintained its size and shape, with easily removable, unstressed body panels, but certain design changes did occur. During the 20-year production life improvements were made on an ongoing basis.
ID 19 submodel to extend brand downwards (1957–69)
The 1955 DS19 was 65% more expensive than the car it replaced, the Citroën Traction Avant. This affected potential sales in a country still recovering economically from World War II, so a cheaper submodel, the Citroën ID, was introduced in 1957.
The ID shared the DS's body but was less powerful and luxurious. Although it shared the engine capacity of the DS engine (at this stage 1,911 cc), the ID provided a maximum power output of only 69 hp compared to the 75 hp claimed for the DS19. Power outputs were further differentiated in 1961 when the DS19 acquired a Weber-32 twin bodied carburettor, and the increasing availability of higher octane fuel enabled the manufacturer to increase the compression ratio from 7.5:1 to 8.5:1. A new DS19 now came with a promised 83 hp of power. The ID19 was also more traditional mechanically: it had no power steering and had conventional transmission and clutch instead of the DS's hydraulically controlled set-up. Initially the basic ID19 was sold on the French market with a price saving of more than 25% against the DS, although the differential was reduced at the end of 1961 when the manufacturer quietly withdrew the entry level ID19 "Normale" from sale. A station wagon variant, the ID Break, was introduced in 1958.
D SPECIAL AND D SUPER (1970–75)
The ID was replaced by the D Spécial and D Super in 1970, but these retained the lower specification position in the range. The D Super was available with the DS21 2175ccm engine and a 5 speed gearbox, and named the D Super 5.
SERIE 2 - NOSE REDESIGN IN 1962
In September 1962, the DS was restyled with a more aerodynamically efficient nose, better ventilation and other improvements. It retained the open two headlamp appearance, but was available with an optional set of driving lights mounted on the front fenders. All models in the range changed nose design at the same time, including the ID and station wagon models.
Series 3 - Nose redesign in 1967 with Directional headlights
In late 1967, for the 1968 model year, the DS and ID was again restyled, by Robert Opron, who also styled the 1970 SM and 1974 CX. This version had a more streamlined headlamp design, giving the car a notably shark-like appearance. This design had four headlights under a smooth glass canopy, and the inner set swivelled with the steering wheel. This allowed the driver to see "around" turns, especially valuable on twisting roads driven at high speed at night.
Behind each glass cover lens, the inboard high-beam headlamp swivels by up to 80° as the driver steers, throwing the beam along the driver's intended path rather than uselessly across the curved road. The outboard low-beam headlamps are self-leveling in response to pitching caused by acceleration and braking.
However, this feature was not allowed in the US at the time (see World Forum for Harmonization of Vehicle Regulations), so a version with four exposed headlights that did not swivel was made for the US market.
This 'turning headlight' feature was new to the market - it had only been seen before on the very rare three headlight 1935 Tatra 77A. The Tucker, which never was mass-produced, had a central headlight that turned with the steering. 45 years later, it is now a commonly available feature, even in the United States.
NEW GREEN HYDRAULIC FLUID
The original hydropneumatic system used a vegetable oil liquide hydraulique végétal (LHV), similar to that used in other cars at the time, but later switched to a synthetic fluid liquide hydraulique synthétique (LHS). Both of these had the disadvantage that they are hygroscopic, as is the case with most brake fluids. Disuse allows water to enter the hydraulic components causing deterioration and expensive maintenance work. The difficulty with hygroscopic hydraulic fluid was exacerbated in the DS/ID due to the extreme rise and fall in the fluid level in the reservoir, which went from nearly full to nearly empty when the suspension extended to maximum height and the six accumulators in the system filled with fluid. With every "inhalation" of fresh moisture- (and dust-) laden air, the fluid absorbed more water.
For the 1967 model year, Citroën introduced a new mineral oil-based fluid LHM (Liquide Hydraulique Minéral). This fluid was much less harsh on the system. LHM remained in use within Citroën until the Xantia was discontinued in 2001.
LHM required completely different materials for the seals. Using either fluid in the incorrect system would completely destroy the hydraulic seals very quickly. To help avoid this problem, Citroën added a bright green dye to the LHM fluid and also painted all hydraulic elements bright green. The former LHS parts were painted black.
All models, including the station wagon and ID, were upgraded at the same time. The hydraulic fluid changed to the technically superior LHM in all markets except the US and Canada, where the change did not take place until January 1969, due to local regulations.
INTERNATIONAL SALES AND PRODUCTION
The DS was primarily manufactured at the Quai André-Citroën in the Javel neighborhood of Paris, with other manufacturing facilities in the United Kingdom, South Africa, the former Yugoslavia (mostly Break Ambulances), and Australia.
Australia constructed their own D variant in the 1960s at Heidelberg, Victoria, identified as the ID 19 "Parisienne." Australian market cars were fitted with options as standard equipment such as the "DSpecial DeLuxe" that were not available on domestic European models.
Until 1965, cars were assembled at the manufacturer's Slough premises, to the west of London, using a combination of French made knock down kits and locally sourced components, some of them machined on site. A French electrical system superseded the British one on the Slough cars in 1962, giving rise to a switch to "continental style" negative earthing. After 1965 cars for the British market were imported fully assembled from the company's French plant. The British-built cars are distinguished by their leather seats, wooden (early ID19 models) one piece plastic (early DS19 models) dashboards, chromed number plate mount let into the front bumper, and (on pre-1962 cars) Lucas-made electrics. These were all right hand drive cars.
The DS was built and sold in South Africa from 1959 to 1975.
The DS was sold in Japan, but the models were built in France and left hand drive.
DS IN NORTH AMERICA
The DS was sold in North America from 1956 to 1972. Despite its popularity in Europe, it didn't sell well in the United States, and little better in Canada. While promoted as a luxury car, it did not have the basic features that American buyers expected to find on such a vehicle, such as an automatic transmission, air conditioning, power windows, or a powerful engine. The DS was designed specifically to address the French market, with punitive tax horsepower taxation of large engines, as well as very poor roads – it's no great mystery that it was a fish out of water when those constraints were removed.
Jay Leno described the sporadic supply of spare parts as a problem for 1970s era customers, based on his early experiences working at a Citroën dealer in Boston.
The DS was expensive, with a 115 hp (86 kW) vehicle costing $4,170 in 1969, when the price was $4,500 for a 360 hp (268 kW) Buick Electra 225 4 door sedan. For all years, 38,000 units were sold.
US regulations at the time also banned one of the car's more advanced features: its composite headlamps with aerodynamic covered lenses. Based on legislation that dated from 1940, all automobiles sold in the U.S. were required to have round, sealed beam headlamps that produced a meager 75,000 candlepower. The powerful quartz iodine swiveling headlamps designed for the 1968 model DS represented so many performance improvements at once that they were far beyond what the regulations could allow.[50] Even the aerodynamic headlight covers were illegal – as seen on the 1968 Jaguar E-Type. It took the lobbying muscle of Ford to point out that the government was requiring two contradictory things – safety, by ensuring that all headlights were best-of-breed circa 1940, and fuel economy through the CAFE standard – by definition, cars with poor aerodynamics are sacrificing fuel economy. Composite bulb lamps and aerodynamic covered headlights were not permitted until 1983.
The European lamps were legal in Canada, including the directional headlamps.
The hydraulic fluid change in 1967 was another brain teaser for U.S. automotive regulators at the Department of Transportation. NHTSA follows the precautionary principle, also used by the Food and Drug Administration, where new innovations are prohibited until their developers can prove them to the regulators; this stifles the experimentation that automakers need to advance their products. NHTSA had already approved a brake fluid they considered safe – DOT 3 brake fluid, which is red and hygroscopic to promote internal rust. This completely different fluid, used in aircraft applications – the technically superior green LHM (Liquide Hydraulique Mineral) – took NHTSA two years to analyze for automotive use. Approval finally came in January 1969, so half the U.S. cars of the 1969 model year use red fluid and half use green fluid.
DESIGN VARIATIONS
PALLAS
In 1965 a luxury upgrade, the DS Pallas (after Greek goddess Pallas), was introduced. This included comfort features such as better noise insulation, a more luxurious (and optional leather) upholstery and external trim embellishments. From 1966 the Pallas model received a driver's seat with height adjustment.
STATION WAGON, FAMILIALE AND AMBULANCE
A station wagon version was introduced in 1958. It was known by various names in different markets (Break in France, Safari and Estate in the UK, Wagon in the US, and Citroën Australia used the terms Safari and Station-Wagon). It had a steel roof to support the standard roof rack. 'Familiales' had a rear seat mounted further back in the cabin, with three folding seats between the front and rear squabs. The standard Break had two side-facing seats in the main load area at the back.
The Ambulance configuration was similar to that of the Break, but with a 60/30 split in the rear folding seat to accommodate a stretcher. A 'Commerciale' version was also available for a time.
The Safari saw use as a camera car, notably by the BBC. The hydropneumatic suspension produces an unusually steady platform for filming while driving.
CONVERTIBLE
Rarest and most collectable of all DS variants, a convertible was offered from 1958 until 1973. The Cabriolet d'Usine (factory convertible) were built by French carrossier Henri Chapron, for the Citroën dealer network. It was an expensive car, so only 1,365 were sold. These DS convertibles used a special frame which was reinforced on the sidemembers and rear suspension swingarm bearing box, similar to, but not identical to the Break (Station Wagon) frame.
CHAPRON VARIATIONS
In addition, Chapron also produced a few coupés, non-works convertibles and special sedans (including the "Prestige", same wheelbase but with a central divider, and the "Lorraine" notchback).
BOSSAERT COUPE
Between 1959 and 1964, Hector Bossaert produced a coupé on a DS chassis shortened by 470 mm. While the front end remained unchanged, the rear end featured notchback styling.
THE REACTOR
In 1965, noted American auto customizer Gene Winfield created The Reactor, a Citroën DS chassis, with a turbocharged 180 hp (130 kW) flat-six engine from the Corvair driving the front wheels. Since the DS already had the engine behind the front wheels, the longer engine meant only one row of seats. This was draped in a streamlined, low slung, aluminum body.
The Reactor was seen in American Television programs of the era, such as Star Trek: The Original Series episode 2.25 ("Bread and Circuses)," Batman episodes 110 ("Funny Feline Felonies") and 111 (driven by Catwoman Eartha Kitt), and Bewitched, which devoted its episode 3.19 ("Super Car") to The Reactor.
MICHELIN PLR
The Michelin PLR is a mobile tire evaluation machine, based on the DS Break, built in 1972, later used for promotion.
Technical details
SUSPENSION
In a hydropneumatic suspension system, each wheel is connected, not to a spring, but to a hydraulic suspension unit consisting of a hydraulic accumulator sphere of about 12 cm in diameter containing pressurised nitrogen, a cylinder containing hydraulic fluid screwed to the suspension sphere, a piston inside the cylinder connected by levers to the suspension itself, and a damper valve between the piston and the sphere. A membrane in the sphere prevented the nitrogen from escaping. The motion of the wheels translated to a motion of the piston, which acted on the oil in the nitrogen cushion and provided the spring effect. The damper valve took place of the shock absorber in conventional suspensions. The hydraulic cylinder was fed with hydraulic fluid from the main pressure reservoir via a height corrector, a valve controlled by the mid-position of the anti-roll bar connected to the axle. If the suspension was too low, the height corrector introduced high-pressure fluid; if it was too high, it released fluid back to the fluid reservoir. In this manner, a constant ride height was maintained. A control in the cabin allowed the driver to select one of five heights: normal riding height, two slightly higher riding heights for poor terrain, and two extreme positions for changing wheels. (The correct term, oleopneumatic (oil-air), has never gained widespread use. Hydropneumatic (water-air) continues to be preferred overwhelmingly.)
The DS did not have a jack for lifting the car off the ground. Instead, the hydraulic system enabled wheel changes with the aid of a simple adjustable stand. To change a flat tyre, one would adjust the suspension to its topmost setting, insert the stand into a special peg near the flat tyre, then readjust the suspension to its lowermost setting. The flat tyre would then retract upwards and hover above ground, ready to be changed. This system, used on the SM also, was superseded on the CX by a screw jack that, after the suspension was raised to the high position, lifted the tire clear of the ground. The DS system, while impressive to use, sometimes dropped the car quite suddenly, especially if the stand was not placed precisely or the ground was soft or unlevel.
SOURCE AND RESERVE OF PRESSURE
The central part of the hydraulic system was the high pressure pump, which maintained a pressure of between 130 and 150 bar in two accumulators. These accumulators were very similar in construction to the suspension spheres. One was dedicated to the front brakes, and the other ran the other hydraulic systems. (On the simpler ID models, the front brakes operated from the main accumulator.) Thus in case of a hydraulic failure, the first indication would be that the steering became heavy, followed by the gearbox not working; only later would the brakes fail.
Two different hydraulic pumps were used. The DS used a seven-cylinder axial piston pump driven off two belts and delivering 175 bar (2,540 psi) of pressure. The ID19, with its simpler hydraulic system, had a single-cylinder pump driven by an eccentric on the camshaft.
GEARBOX AND CLUTCH
HYDRAULIQUE OR CITROMATIC
The DS was initially offered only with the "hydraulique" four-speed semi-automatic (bvh—"boîte de vitesses hydraulique") gearbox.
This was a four-speed gearbox and clutch, operated by a hydraulic controller. To change gears, the driver flicked a lever behind the steering wheel to the next position and eased-up on the accelerator pedal. The hydraulic controller disengaged the clutch, engaged the nominated gear, and re-engaged the clutch. The speed of engagement of the clutch was controlled by a centrifugal regulator sensing engine rpm and driven off the camshaft by a belt, the position of the butterfly valve in the carburettor (i.e., the position of the accelerator), and the brake circuit. When the brake was pressed, the engine idle speed dropped to an rpm below the clutch engagement speed, thus preventing friction while stopped in gear at traffic lights. When the brake was released, the idle speed increased to the clutch dragging speed. The car would then creep forward much like automatic transmission cars. This drop in idle throttle position also caused the car to have more engine drag when the brakes were applied even before the car slowed to the idle speed in gear, preventing the engine from pulling against the brakes. In the event of loss of hydraulic pressure (following loss of system fluid), the clutch would disengage, to prevent driving, while brake pressure reserves would allow safe braking to standstill.
MANUAL - FOUR SPEED AND FIVE-SPEED
The later and simpler ID19 had the same gearbox and clutch, manually operated. This configuration was offered as a cheaper option for the DS in 1963. The mechanical aspects of the gearbox and clutch were completely conventional and the same elements were used in the ID 19. In September 1970, Citroën introduced a five-speed manual gearbox, in addition to the original four-speed unit.
FULLY AUTOMATIC
In September 1971 Citroën introduced a 3-speed fully automatic Borg-Warner 35 transmission gearbox, on the DS 21 and later DS 23 models. It is ironic that the fully automatic transmission DS was never sold in the US market, where this type of transmission had gained market share so quickly that it became the majority of the market by this time. Many automatic DSs, fuel-injected DS 23 sedans with air conditioning, were sold in Australia.
ENGINES
The DS was originally designed around an air-cooled flat-six based on the design of the 2-cylinder engine of the 2CV, similar to the motor in the Porsche 911. Technical and monetary problems forced this idea to be scrapped.
Thus, for such a modern car, the engine of the original DS 19 was also old-fashioned. It was derived from the engine of the 11CV Traction Avant (models 11B and 11C). It was an OHV four-cylinder engine with three main bearings and wet liners, and a bore of 78 mm and a stroke of 100 mm, giving a volumetric displacement of 1911 cc. The cylinder head had been reworked; the 11C had a reverse-flow cast iron cylinder head and generated 60 hp (45 kW) at 3800 rpm; by contrast, the DS 19 had an aluminium cross-flow head with hemispherical combustion chambers and generated 75 hp (56 kW) at 4500 rpm.
Like the Traction Avant, the DS had the gearbox mounted in front of the engine, with the differential in between. Thus some consider the DS to be a mid engine front-wheel drive car.
The DS and ID powerplants evolved throughout its 20-year production life. The car was underpowered and faced constant mechanical changes to boost the performance of the four-cylinder engine. The initial 1911 cc three main bearing engine (carried forward from the Traction Avant) of the DS 19 was replaced in 1965 with the 1985 cc five-bearing wet-cylinder motor, becoming the DS 19a (called DS 20 from September 1969).
The DS 21 was also introduced for model year 1965. This was a 2175 cc, five main bearing engine; power was 109 hp This engine received a substantial increase in power with the introduction of Bosch electronic fuel injection for 1970, making the DS one of the first mass-market cars to use electronic fuel injection. Power of the carbureted version also increased slightly at the same time, owing to the employment of larger inlet valves.
Lastly, 1973 saw the introduction of the 2347 cc engine of the DS 23 in both carbureted and fuel-injected forms. The DS 23 with electronic fuel injection was the most powerful production model, producing 141 hp (105 kW).
IDs and their variants went through a similar evolution, generally lagging the DS by about one year. ID saloon models never received the DS 23 engine or fuel injection, although the Break/Familiale versions received the carburetted version of the DS 23 engine when it was introduced, supplemented the DS20 Break/Familiale.
The top of the range ID model, The DSuper5 (DP) gained the DS21 engine (the only model that this engine was retained in) for the 1973 model year and it was mated to a five-speed gearbox. This should not be confused with the 1985 cc DSuper fitted with an optional "low ratio" five-speed gearbox, or with the previous DS21M (DJ) five-speed.
IN POPULAR CULTURE
President Charles de Gaulle survived an assassination attempt at Le Petit-Clamart near Paris on August 22, 1962, planned by Algerian War veteran Jean-Marie Bastien-Thiry. The plan was to ambush the motorcade with machine guns, disable the vehicles, and then close in for the kill. De Gaulle praised the unusual abilities of his unarmoured DS with saving his life – the car was peppered with bullets, and the shots had punctured the tyres, but the car could still escape at full speed. This event was accurately recreated in the 1973 film The Day of the Jackal.
Beyond de Gaulle and the French aristocracy, the roomy DS also appealed to French taxi drivers.
Outside France, the car drew an eclectic customer mix, such as Cosmonaut Yuri Gagarin, Pope John XXIII, painter Marc Chagall, and actors Ken Berry, Jeff Bridges, and Rosamund Pike.
The DS appeared in several episodes of contemporary television series Mission: Impossible, including substantial appearances in 'The Slave' (ep. 2.06) and 'Robot' (ep. 4.09).
An ode to Jane Child's DS21 appears on her 1989 self-titled album.
In 1989, the film Back to the Future Part II featured a modified Citroen DS as a flying taxicab, when the main characters travel 30 years into the future (2015). Scarface (1983 film) with Al Pacino and the 2009 television series The Mentalist both feature the DS in key roles. According to Internet Movie Cars Database, the DS/ID has made over 2,000 film and television appearances so far.
Two films focus on the DS, including The Goddess of 1967 about a Japanese man purchasing a DS (goddess or déesse in French) in Australia, and 1995's Icelandic-Japanese road movie Cold Fever.
LEGACY
Citroën DS values have been rising – a 1973 DS 23 Injection Electronique "Decapotable" (Chapron Convertible) sold for EUR €176,250 (USD $209,738) at Christie's Rétromobile in February 2006. and a similar car sold by Bonhams in February 2009 brought EUR €343,497 (USD $440,436). On 18 September 2009 a 1966 DS21 Decapotable Usine was sold by Bonhams for a hammer price of UK£131,300. Bonhams sold another DS21 Decapotable (1973) on 23 January 2010 for EUR €189,000.
The DS's beloved place in French society was demonstrated in Paris on 9 October 2005 with a celebration of the 50th anniversary of its launch. 1,600 DS cars drove in procession past the Arc de Triomphe.
From 2005 to 2008, a young Frenchman named Manuel Boileau travelled around the world in a 1971 DS ambulance. It was an 80,000 kilometer journey across 38 countries called Lunaya World Tour. While traveling through Laos, he located the forlorn 1974 DS Prestige belonging to Sisavang Vatthana, the last King of the Kingdom of Laos, which is now preserved and restored by specialists in Bangkok.
In 2009, Groupe PSA created a new brand - DS Automobiles, intended as high quality, high specification variations on existing models, with differing mechanics and bodywork. This brand ranges across four models, the DS3, DS4, DS5, and the China-only SUV DS 6. The DS3, launched in March 2010, is based on Citroen's new C3, but is more customisable and unique, bearing some resemblance to the original DS, with its "Shark Fin" side pillar. These have created their own niches, with the DS4 being a mix of a crossover and a coupe and the DS5 mixing a coupe and an estate. Many feature hybrid-diesel engines to maximise efficiency.

Some background:
At the end of WW2, Sweden was in search of a new fighter offering better performance than the J21 could offer. The latter was an indigenous fighter/attack aircraft from SAAB that first took to the air in 1943 and dated back to a requirement from 1941. The J21 was designed as an unusual twin boom pusher configuration, where the propeller was mounted in the rear of the fuselage, pushing the aircraft forward. The advantages of a pusher design were that the view forward was unobstructed and armament could be concentrated in the nose, while the heavy engine was placed close to the center of gravity for better handling and agility. A major drawback was the difficulty in escaping from the aircraft in an emergency, though, as the pilot could get drawn into the propeller blades. SAAB deliberated between systems that would eject the pilot, or jettison the propeller or even the whole engine, via a system of explosive bolts, and eventually installed an early, explosives-powered ejector seat developed by Bofors for this purpose.
However, the SAAB 21 had its share of trouble (overheating an unreliable DB 605 engine), and in 1944 a new requirement for a more powerful and conventional fighter was issued. Selecting the Rolls Royce Griffon as the powerplant, SAAB initially looked into adapting the engine to the J21. However, this proved impractical, so SAAB started work on a clean-sheet design.
The L27, as it was known in the project stage, ended up closely resembling the latest designs to come from Britain like the Supermarine Spitfire or the Martin Baker MB 5, as well as the North American P-51 Mustang. The Griffon engine, chosen for initial development and flight tests, drove a contra-rotating propeller and sat in the nose. Top speed with the Griffon was expected to be around 700 km/h (435 mph). Later production aircraft were to be powered by a domestically developed, new H-24 cylinder motor similar to the British Napier Sabre engine and delivering output in significant excess of 2.200 hp (1.640 kW). With this machine, the aircraft was expected to reach a top speed of 740 km/h (460 mph) or even more.
The wings were similar to those used on the Fairey Firefly, complete with Fairey’s characteristic Youngman flaps, but with small wing root extensions and a thicker profile than the late Spitfires’ wings, and with more rounded wing tips. Similar to the P-51, the L27’s landing gear with a wide track retracted inwards into the wings, and the tail wheel could be fully retracted, too.
Armament, consisting of four 20mm Hispano cannons, was to be concentrated in the wings just outside of the propeller arc, and unlike the Spitfire’s arrangement with underwing coolers, the L27’s single radiator was placed in a ventral tunnel position, very similar to the arrangement on the P-51.
A total of three prototypes were ordered, and the aircraft was now formally designated J27A; two were to be powered by Rolls-Royce Griffon 83 engines, and one as a test structure and earmarked for the development of the 24 cylinder engine and its integration into the projected J27B.
The first flight of a J27A took place in March 1945, and the promising results kept the project evolving until late 1946, when the aircraft was cleared for service and production in January 1947. 70 aircraft with Griffon engines were ordered.
Anyway, in early 1945, SAAB had also launched a project to determine how to provide the J21A with a jet engine to get the experience of jet engines and flying at high speeds. The goal was to catch up with the development of jet aircraft, which were moving ahead fast in England, where, among others, de Havilland already had the de Havilland Vampire in production. The resulting J21R, SAAB's first jet, made its first flight on 10 March 1947 and it marked the death knell for any piston-engine fighter development and use in Sweden. Consequentially the 24 cylinder engine never made it from the drawing board, and after the initial production run of the Griffon-powered J27A was completed until early 1949, further production was stopped and the whole J27 program terminated. Serial production J27As differed only slightly from the prototypes. The most obvious change was a taller vertical stabilizer and a small fin fillet, less obvious was a modified landing gear cover arrangement, because the original design with a single, large cover of the main wheels tended to bulge outward at high speed. A split design mended this problem.
While the J27A’s projected top speed of 700km/h was impressive for a piston-engine fighter and frequently confirmed in service, it was inadequate in the oncoming jet age. In the end, SAAB opted to pursuit jet fighter endeavors that soon led to the very modern and innovative SAAB J29 that soon became Sweden’s standard jet fighter.
In frontline service the J27 was, even though it was popular among its pilots and maintenance crews, almost immediately replaced by jets, at first with the J28B Vampire (from 1951 on), which were in turn quickly replaced in 1952 with the indigenous J29 Tunnan.
The last J27A was, after serving with fighter units primarily in southern Sweden, already retired from frontline duties in 1955. Some aircraft, though, were kept in service as target tugs, liaison aircraft for the air staff and for dissimilar air combat training. The last machine was finally decommissioned in summer 1961.

The kit and its assembly:
This is a “real” what-if model, or at least the attempt to build a phantom aircraft from single parts! The SAAB 27 is a bit of a mystery, because valid information is sparse, especially concerning details about its shape. You find some drawings or profiles, but IMHO these are based on guesswork and rather vague. The J27 is frequently described as a “Swedish Spitfire with a P-51 radiator” or a “Swedish Super-Spitfire”, but that leaves much to be desired, because the similarity is only superficial. Hence, this model here is rather a free interpretation of what a service J27 could have looked like.
For long time I fought with two building options: either convert a Fairey Firefly (Airfix’ Mk. 5 would have been my bet), or use a Spitfire Mk. 22. After long considerations I settled for the latter one, because I feared that the Firefly would result in a rather massive aircraft, and the Airfix kit itself is vintage and worth a building fight on its own.
So I used an Airfix Spitfire Mk. 22, but from this (very nice!) kit just a few things were taken, because I wanted a more individual look. Only the fuselage, cockpit interior and landing gear survived, and I even inserted a 2.5mm wide “wedge plug” around the cockpit and wedge-shaped inserts at the fuselage halves’ seams in order to add some beef to the sleek (if not spindly) Spitfire. I think it’s hard to notice, but the overall proportions look good. At the tail and the front end, the original fuselage width was kept, though.
Reason behind this was the P-51 radiator’s width (leftover from a Matchbox kit) that was considerably wider than the Spitfire fuselage. Furthermore, the thicker/more massive wings from a P-47 (from an early MPM kit) also called for a more massive body.
For the new wings, some adaptations to the Spitfire wing roots had to be made, though, e.g. a bulged mid-wing section under the fuselage. The Thunderbolt parts also had the benefit of wells for a landing gear that retracts inwards. I also used P-47 landing gear parts, even though the struts were shortened at their bases by 3mm and the covers accordingly. For the sake of a different look (the Spitfire wheels are very characteristic) I used different main wheels from a Revell G.91R. The landing gear cover arrangement differs from J27 sketches (as far as I can tell, it must have been similar to the P-51's), but I stuck with the P-47 parts because they match well with the rest of the aircraft.
The contraprop belongs to a late mark Seafire, left over from a Special Hobby kit. The propeller was in so far modified that I added a metal axis and a styrene tube adapter for the fuselage, so that both propeller parts can (theoretically) spin. OOB, the Special Hobby solution is simply to be glued onto the nose, fixed, despite being constructed in two separate parts?
Furthermore, the carburetor intake was changed: the Spitfire’s scoop at the wings’ leading edge was replace by a Firefly-style lip intake right behind the propeller.
The whole tail section was reconditioned, too. Descriptions of the J27’s tail are corny, but “more square than a Spitfire’s”. Instead of simple cosmetic surgery I thoroughly replaced the OOB fin with a Supermarine Attacker’s (Novo kit) with some mods to the outline, which fits well in size and is …more square!
The new tail is a bit taller and has a fin fillet, making it look very P-51-ish, but that’s O.K. for me. At least it’s different from the round Spitfire shape.
I also exchanged the stabilizers, the round Spitfire parts gave way to differently shaped pieces from a Hobby Boss La-7. Their shape is similar to a P-47’s, but they are smaller and match J27 illustrations well.
The canopy was also changed. Through the widened fuselage around the cockpit the tight OOB Spitfire hood would hardly match, anyway. The bubble layout remained, and I adapted a bigger Matchbox P-51 canopy to the new fuselage contours, and moved forward as far as possible.
Painting and markings:
The Swedish Air Force as operator was settled, as well as early post-WWII markings. But I did not want the standard, uniform olive green/blue grey livery, so I painted the upper surfaces with camouflage scheme made from two green tones: a medium green tone (Humbrol 102, Army Green, ~FS 34096) and a bluish, dark green (Humbrol 91, RLM 70 equivalent), applied in bands – somewhat inspired by a scheme carried by some SAAB 32 Lansen in the early 60ies.
The underside was kept in the typical Swedish blue-grey, for which I used Humbrol 87. The waterline was placed very low so that the upper camouflage was also taken to the radiator flanks under the fuselage and wings.
The cockpit was painted in very dark grey (Humbrol 32), while the landing gear and the wells were kept in Aluminum (Humbrol 56).
As a 2nd squadron machine, the code letter became blue, as well as the two-part spinner, latter’s paint was mixed, based on the squadron code letter decal’s tone on the tail.
The roundels and the 'R' codes come from an RBD Studio aftermarket sheet from Sweden, further decals like the yellow ‘9’ code, the squadron’s ‘Bonzo’ dog mascot emblem as well as most stencils come from a Heller SAAB 21.
A complex build, yet the model aircraft looks so innocent… Anyway, the goal was IMHO achieved: this J27 model just looks like a “Swedish Spitfire with a P-51 radiator”, and at first glance you cannot be certain if this is a modified Griffon Spitfire or a P-51D. Both is true, to a certain degree, but also not correct, because the changes are more fundamental and the wings are completely different from either. So, the mission’s been accomplished. ;)
And I feel inclined to tackle a J23, too, a Bf109/P-51B design hybrid that was designed as a conservative alternative to the pusher J21.

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!
Some background:
At the end of WW2, Sweden was in search of a new fighter offering better performance than the J21 could offer. The latter was an indigenous fighter/attack aircraft from SAAB that first took to the air in 1943 and dated back to a requirement from 1941. The J21 was designed as an unusual twin boom pusher configuration, where the propeller was mounted in the rear of the fuselage, pushing the aircraft forward. The advantages of a pusher design were that the view forward was unobstructed and armament could be concentrated in the nose, while the heavy engine was placed close to the center of gravity for better handling and agility. A major drawback was the difficulty in escaping from the aircraft in an emergency, though, as the pilot could get drawn into the propeller blades. SAAB deliberated between systems that would eject the pilot, or jettison the propeller or even the whole engine, via a system of explosive bolts, and eventually installed an early, explosives-powered ejector seat developed by Bofors for this purpose.
However, the SAAB 21 had its share of trouble (overheating an unreliable DB 605 engine), and in 1944 a new requirement for a more powerful and conventional fighter was issued. Selecting the Rolls Royce Griffon as the powerplant, SAAB initially looked into adapting the engine to the J21. However, this proved impractical, so SAAB started work on a clean-sheet design.
The L27, as it was known in the project stage, ended up closely resembling the latest designs to come from Britain like the Supermarine Spitfire or the Martin Baker MB 5, as well as the North American P-51 Mustang. The Griffon engine, chosen for initial development and flight tests, drove a contra-rotating propeller and sat in the nose. Top speed with the Griffon was expected to be around 700 km/h (435 mph). Later production aircraft were to be powered by a domestically developed, new H-24 cylinder motor similar to the British Napier Sabre engine and delivering output in significant excess of 2.200 hp (1.640 kW). With this machine, the aircraft was expected to reach a top speed of 740 km/h (460 mph) or even more.
The wings were similar to those used on the Fairey Firefly, complete with Fairey’s characteristic Youngman flaps, but with small wing root extensions and a thicker profile than the late Spitfires’ wings, and with more rounded wing tips. Similar to the P-51, the L27’s landing gear with a wide track retracted inwards into the wings, and the tail wheel could be fully retracted, too.
Armament, consisting of four 20mm Hispano cannons, was to be concentrated in the wings just outside of the propeller arc, and unlike the Spitfire’s arrangement with underwing coolers, the L27’s single radiator was placed in a ventral tunnel position, very similar to the arrangement on the P-51.
A total of three prototypes were ordered, and the aircraft was now formally designated J27A; two were to be powered by Rolls-Royce Griffon 83 engines, and one as a test structure and earmarked for the development of the 24 cylinder engine and its integration into the projected J27B.
The first flight of a J27A took place in March 1945, and the promising results kept the project evolving until late 1946, when the aircraft was cleared for service and production in January 1947. 70 aircraft with Griffon engines were ordered.
Anyway, in early 1945, SAAB had also launched a project to determine how to provide the J21A with a jet engine to get the experience of jet engines and flying at high speeds. The goal was to catch up with the development of jet aircraft, which were moving ahead fast in England, where, among others, de Havilland already had the de Havilland Vampire in production. The resulting J21R, SAAB's first jet, made its first flight on 10 March 1947 and it marked the death knell for any piston-engine fighter development and use in Sweden. Consequentially the 24 cylinder engine never made it from the drawing board, and after the initial production run of the Griffon-powered J27A was completed until early 1949, further production was stopped and the whole J27 program terminated. Serial production J27As differed only slightly from the prototypes. The most obvious change was a taller vertical stabilizer and a small fin fillet, less obvious was a modified landing gear cover arrangement, because the original design with a single, large cover of the main wheels tended to bulge outward at high speed.

The Citroën DS (French pronunciation: [si.tʁɔ.ˈɛn de ɛs]) is a front-engine, front-wheel-drive executive car manufactured and marketed by the French company Citroën from 1955 to 1975 in sedan, wagon/estate and convertible body configurations. Italian sculptor and industrial designer Flaminio Bertoni and the French aeronautical engineer André Lefèbvre styled and engineered the car. Paul Magès developed the hydropneumatic self-levelling suspension.
Noted for its aerodynamic, futuristic body design and innovative technology, the DS set new standards in ride quality, handling, and braking—and was the first production car equipped with disc brakes.
Citroën sold 1,455,746 examples, including 1,330,755 built at the manufacturer's Paris Quai André-Citroën production plant.
The DS came third in the 1999 Car of the Century poll recognizing the world's most influential auto designs and was named the most beautiful car of all time by Classic & Sports Car magazine
MODEL HISTORY
After 18 years of secret development as the successor to the Traction Avant, the DS 19 was introduced on 5 October 1955 at the Paris Motor Show. In the first 15 minutes of the show, 743 orders were taken, and orders for the first day totalled 12,000. During the 10 days of the show, the DS took in 80,000 deposits; a record that has stood for over 60 years.
Contemporary journalists said the DS pushed the envelope in the ride vs. handling compromise possible in a motor vehicle.
To a France still deep in reconstruction after the devastation of World War II, and also building its identity in the post-colonial world, the DS was a symbol of French ingenuity. The DS was distributed to many territories throughout the world.
It also posited the nation's relevance in the Space Age, during the global race for technology of the Cold War. Structuralist philosopher Roland Barthes, in an essay about the car, said that it looked as if it had "fallen from the sky". An American advertisement summarised this selling point: "It takes a special person to drive a special car".
Because they were owned by the technologically aggressive tire manufacturer Michelin, Citroën had designed their cars around the technically superior radial tire since 1948, and the DS was no exception.
The car featured a novel hydropneumatic suspension including an automatic leveling system and variable ground clearance, developed in-house by Paul Magès. This suspension allowed the DS to travel quickly on the poor road surfaces common in France.
In addition, the vehicle had power steering and a semi-automatic transmission (the transmission required no clutch pedal, but gears still had to be shifted by hand), though the shift lever controlled a powered hydraulic shift mechanism in place of a mechanical linkage, and a fibreglass roof which lowered the centre of gravity and so reduced weight transfer. Inboard front brakes (as well as independent suspension) reduced unsprung weight. Different front and rear track widths and tyre sizes reduced the unequal tyre loading, which is well known to promote understeer, typical of front-engined and front-wheel drive cars.
As with all French cars, the DS design was affected by the tax horsepower system, which effectively mandated very small engines. Unlike the Traction Avant predecessor, there was no top-of-range model with a powerful six-cylinder engine. Citroën had planned an air-cooled flat-6 engine for the car, but did not have the funds to put the prototype engine into production.
The DS placed third in the 1999 Car of the Century competition, and fifth on Automobile Magazine's "100 Coolest Cars" listing in 2005. It was also named the most beautiful car of all time by Classic & Sports Car magazine after a poll of 20 world-renowned car designers, including Giorgetto Giugiaro, Ian Callum, Roy Axe, Paul Bracq, and Leonardo Fioravanti.
NAME
Both the DS and its simpler sibling, the ID, used a punning name. "DS" is pronounced in French as "Déesse" (goddess); "ID" is pronounced as "Idée" (idea). An intermediate model was called the DW.
MOTORSPORT
The DS was successful in motorsports like rallying, where sustained speeds on poor surfaces are paramount, and won the Monte Carlo Rally in 1959. In the 1000 Lakes Rally, Pauli Toivonen drove a DS19 to victory in 1962.
In 1966, the DS won the Monte Carlo Rally again, with some controversy as the competitive BMC Mini-Cooper team was disqualified due to rule infractions. Ironically, Mini was involved with DS competition again two years later, when a drunk driver in a Mini in Sydney Australia crashed into the DS that was leading the 1968 London–Sydney Marathon, 98 miles from the finish line. The DS was still competitive in the grueling 1974 London-Sahara-Munich World Cup Rally, where it won over 70 other cars, only 5 of which even completed the entire event.
TECHNICAL INNOVATION - HYDRAULIC SYSTEMS
In conventional cars, hydraulics are only used in brakes and power steering. In the DS they were also used for the suspension, clutch and transmission. The cheaper 1957 ID19 did have manual steering and a simplified power-braking system. An engine driven pump pressurizes the closed system to 2,400 pounds per square inch.
At a time when few passenger vehicles had independent suspension on all wheels, the application of the hydraulic system to the car's suspension system to provide a self-levelling system was an innovative move. This suspension allowed the car to achieve sharp handling combined with very high ride quality, frequently compared to a "magic carpet".
The hydropneumatic suspension used was pioneered the year before, on the rear of another car from Citroën, the top of range Traction Avant 15CV-H.
IMPACT ON CITROEN BRAND DEVELOPMENT
The 1955 DS cemented the Citroën brand name as an automotive innovator, building on the success of the Traction Avant, which had been the world's first mass-produced unitary body front-wheel-drive car in 1934. In fact, the DS caused such a huge sensation that Citroën was apprehensive that future models would not be of the same bold standard. No clean sheet new models were introduced from 1955 to 1970.
The DS was a large, expensive executive car and a downward brand extension was attempted, but without result. Throughout the late 1950s and 1960s Citroën developed many new vehicles for the very large, profitable market segments between the 2CV and the DS, occupied by vehicles like the Peugeot 403, Renault 16 and Ford Cortina, but none made it into production. Either they had uneconomic build costs, or were ordinary "me too" cars, not up to the company's high standard of innovation. As Citroën was owned by Michelin from 1934 to 1974 as a sort of research laboratory, such broad experimentation was possible. Michelin after all was getting a powerful advertisement for the capabilities of the radial tire Michelin had invented, when such experimentation was successful.
New models based on the small, utilitarian 2CV economy car were introduced, notably the 1961 Ami. It was also designed by Flaminio Bertoni and aimed to combine Three-box styling with the chassis of the 2CV. The Ami was very successful in France, but less so on export markets. Many found the styling controversial, and the car noisy and underpowered. The Dyane, was a modernised 2CV with a hatchback, competed with the 2CV inspired Renault 4 Hatchback. All these 2 cylinder models were very small, so there remained a wide market gap to the DS range all through the 1960s.
In 1970, Citroën finally introduced a car to target the mid-range - the Citroën GS, which won the "European car of the Year" for 1971 and sold 2.5 million units. It combined a small 55 horsepower flat-4 air-cooled engine with Hydropneumatic suspension. The intended 106 horsepower Wankel rotary-engined version with more power did not reach full production.
REPLACING THE DS
The DS remained popular and competitive throughout its production run. Its peak production year was 1970. Certain design elements like the somewhat narrow cabin, column-mounted gearstick, and separate fenders began to seem a little old-fashioned in the 1970s.
Citroën invested enormous resources to design and launch an entirely new vehicle in 1970, the SM, which was in effect a thoroughly modernized DS, with similar length, but greater width. The manual gearbox was a modified DS unit. The front disc brakes were the same design. Axles, wheel bearings, steering knuckles, and hydraulic components were either DS parts or modified DS parts.
The SM had a different purpose than replacing the 15-year-old DS design however - it was meant to launch Citroën into a completely new luxury grand touring market segment. Only fitted with a costly, exotic Maserati engine, the SM was faster and much more expensive than the DS. The SM was not designed to be a practical 4-door saloon suitable as a large family car, the key market for vehicles of this type in Europe. Typically, manufacturers would introduce low-volume coupés based on parts shared with an existing saloon, not as unique models, a contemporary example being the Mercedes-Benz SLC-Class.
The SM's high price and limited utility of the 2+2 seating configuration, meant the SM as actually produced could not seize the mantle from the DS.
So, while the design funds invested would allow the DS to be replaced by two cars - a 'modern DS' and the smaller CX, it was left to the CX alone to provide Citroën's large family or executive car in the model range.
The last DS came off the production line on 24 April 1975 - the manufacturer had taken the elementary precaution of building up approximately eight-month's of inventory of the "break" (estate/station wagon) version of the DS, to cover the period till Autumn 1975 when the estate/station wagon version of the CX would be introduced.
DEVELOPMENT
The DS always maintained its size and shape, with easily removable, unstressed body panels, but certain design changes did occur. During the 20-year production life improvements were made on an ongoing basis.
ID 19 submodel to extend brand downwards (1957–69)
The 1955 DS19 was 65% more expensive than the car it replaced, the Citroën Traction Avant. This affected potential sales in a country still recovering economically from World War II, so a cheaper submodel, the Citroën ID, was introduced in 1957.
The ID shared the DS's body but was less powerful and luxurious. Although it shared the engine capacity of the DS engine (at this stage 1,911 cc), the ID provided a maximum power output of only 69 hp compared to the 75 hp claimed for the DS19. Power outputs were further differentiated in 1961 when the DS19 acquired a Weber-32 twin bodied carburettor, and the increasing availability of higher octane fuel enabled the manufacturer to increase the compression ratio from 7.5:1 to 8.5:1. A new DS19 now came with a promised 83 hp of power. The ID19 was also more traditional mechanically: it had no power steering and had conventional transmission and clutch instead of the DS's hydraulically controlled set-up. Initially the basic ID19 was sold on the French market with a price saving of more than 25% against the DS, although the differential was reduced at the end of 1961 when the manufacturer quietly withdrew the entry level ID19 "Normale" from sale. A station wagon variant, the ID Break, was introduced in 1958.
D SPECIAL AND D SUPER (1970–75)
The ID was replaced by the D Spécial and D Super in 1970, but these retained the lower specification position in the range. The D Super was available with the DS21 2175ccm engine and a 5 speed gearbox, and named the D Super 5.
SERIE 2 - NOSE REDESIGN IN 1962
In September 1962, the DS was restyled with a more aerodynamically efficient nose, better ventilation and other improvements. It retained the open two headlamp appearance, but was available with an optional set of driving lights mounted on the front fenders. All models in the range changed nose design at the same time, including the ID and station wagon models.
Series 3 - Nose redesign in 1967 with Directional headlights
In late 1967, for the 1968 model year, the DS and ID was again restyled, by Robert Opron, who also styled the 1970 SM and 1974 CX. This version had a more streamlined headlamp design, giving the car a notably shark-like appearance. This design had four headlights under a smooth glass canopy, and the inner set swivelled with the steering wheel. This allowed the driver to see "around" turns, especially valuable on twisting roads driven at high speed at night.
Behind each glass cover lens, the inboard high-beam headlamp swivels by up to 80° as the driver steers, throwing the beam along the driver's intended path rather than uselessly across the curved road. The outboard low-beam headlamps are self-leveling in response to pitching caused by acceleration and braking.
However, this feature was not allowed in the US at the time (see World Forum for Harmonization of Vehicle Regulations), so a version with four exposed headlights that did not swivel was made for the US market.
This 'turning headlight' feature was new to the market - it had only been seen before on the very rare three headlight 1935 Tatra 77A. The Tucker, which never was mass-produced, had a central headlight that turned with the steering. 45 years later, it is now a commonly available feature, even in the United States.
NEW GREEN HYDRAULIC FLUID
The original hydropneumatic system used a vegetable oil liquide hydraulique végétal (LHV), similar to that used in other cars at the time, but later switched to a synthetic fluid liquide hydraulique synthétique (LHS). Both of these had the disadvantage that they are hygroscopic, as is the case with most brake fluids. Disuse allows water to enter the hydraulic components causing deterioration and expensive maintenance work. The difficulty with hygroscopic hydraulic fluid was exacerbated in the DS/ID due to the extreme rise and fall in the fluid level in the reservoir, which went from nearly full to nearly empty when the suspension extended to maximum height and the six accumulators in the system filled with fluid. With every "inhalation" of fresh moisture- (and dust-) laden air, the fluid absorbed more water.
For the 1967 model year, Citroën introduced a new mineral oil-based fluid LHM (Liquide Hydraulique Minéral). This fluid was much less harsh on the system. LHM remained in use within Citroën until the Xantia was discontinued in 2001.
LHM required completely different materials for the seals. Using either fluid in the incorrect system would completely destroy the hydraulic seals very quickly. To help avoid this problem, Citroën added a bright green dye to the LHM fluid and also painted all hydraulic elements bright green. The former LHS parts were painted black.
All models, including the station wagon and ID, were upgraded at the same time. The hydraulic fluid changed to the technically superior LHM in all markets except the US and Canada, where the change did not take place until January 1969, due to local regulations.
INTERNATIONAL SALES AND PRODUCTION
The DS was primarily manufactured at the Quai André-Citroën in the Javel neighborhood of Paris, with other manufacturing facilities in the United Kingdom, South Africa, the former Yugoslavia (mostly Break Ambulances), and Australia.
Australia constructed their own D variant in the 1960s at Heidelberg, Victoria, identified as the ID 19 "Parisienne." Australian market cars were fitted with options as standard equipment such as the "DSpecial DeLuxe" that were not available on domestic European models.
Until 1965, cars were assembled at the manufacturer's Slough premises, to the west of London, using a combination of French made knock down kits and locally sourced components, some of them machined on site. A French electrical system superseded the British one on the Slough cars in 1962, giving rise to a switch to "continental style" negative earthing. After 1965 cars for the British market were imported fully assembled from the company's French plant. The British-built cars are distinguished by their leather seats, wooden (early ID19 models) one piece plastic (early DS19 models) dashboards, chromed number plate mount let into the front bumper, and (on pre-1962 cars) Lucas-made electrics. These were all right hand drive cars.
The DS was built and sold in South Africa from 1959 to 1975.
The DS was sold in Japan, but the models were built in France and left hand drive.
DS IN NORTH AMERICA
The DS was sold in North America from 1956 to 1972. Despite its popularity in Europe, it didn't sell well in the United States, and little better in Canada. While promoted as a luxury car, it did not have the basic features that American buyers expected to find on such a vehicle, such as an automatic transmission, air conditioning, power windows, or a powerful engine. The DS was designed specifically to address the French market, with punitive tax horsepower taxation of large engines, as well as very poor roads – it's no great mystery that it was a fish out of water when those constraints were removed.
Jay Leno described the sporadic supply of spare parts as a problem for 1970s era customers, based on his early experiences working at a Citroën dealer in Boston.
The DS was expensive, with a 115 hp (86 kW) vehicle costing $4,170 in 1969, when the price was $4,500 for a 360 hp (268 kW) Buick Electra 225 4 door sedan. For all years, 38,000 units were sold.
US regulations at the time also banned one of the car's more advanced features: its composite headlamps with aerodynamic covered lenses. Based on legislation that dated from 1940, all automobiles sold in the U.S. were required to have round, sealed beam headlamps that produced a meager 75,000 candlepower. The powerful quartz iodine swiveling headlamps designed for the 1968 model DS represented so many performance improvements at once that they were far beyond what the regulations could allow.[50] Even the aerodynamic headlight covers were illegal – as seen on the 1968 Jaguar E-Type. It took the lobbying muscle of Ford to point out that the government was requiring two contradictory things – safety, by ensuring that all headlights were best-of-breed circa 1940, and fuel economy through the CAFE standard – by definition, cars with poor aerodynamics are sacrificing fuel economy. Composite bulb lamps and aerodynamic covered headlights were not permitted until 1983.
The European lamps were legal in Canada, including the directional headlamps.
The hydraulic fluid change in 1967 was another brain teaser for U.S. automotive regulators at the Department of Transportation. NHTSA follows the precautionary principle, also used by the Food and Drug Administration, where new innovations are prohibited until their developers can prove them to the regulators; this stifles the experimentation that automakers need to advance their products. NHTSA had already approved a brake fluid they considered safe – DOT 3 brake fluid, which is red and hygroscopic to promote internal rust. This completely different fluid, used in aircraft applications – the technically superior green LHM (Liquide Hydraulique Mineral) – took NHTSA two years to analyze for automotive use. Approval finally came in January 1969, so half the U.S. cars of the 1969 model year use red fluid and half use green fluid.
DESIGN VARIATIONS
PALLAS
In 1965 a luxury upgrade, the DS Pallas (after Greek goddess Pallas), was introduced. This included comfort features such as better noise insulation, a more luxurious (and optional leather) upholstery and external trim embellishments. From 1966 the Pallas model received a driver's seat with height adjustment.
STATION WAGON, FAMILIALE AND AMBULANCE
A station wagon version was introduced in 1958. It was known by various names in different markets (Break in France, Safari and Estate in the UK, Wagon in the US, and Citroën Australia used the terms Safari and Station-Wagon). It had a steel roof to support the standard roof rack. 'Familiales' had a rear seat mounted further back in the cabin, with three folding seats between the front and rear squabs. The standard Break had two side-facing seats in the main load area at the back.
The Ambulance configuration was similar to that of the Break, but with a 60/30 split in the rear folding seat to accommodate a stretcher. A 'Commerciale' version was also available for a time.
The Safari saw use as a camera car, notably by the BBC. The hydropneumatic suspension produces an unusually steady platform for filming while driving.
CONVERTIBLE
Rarest and most collectable of all DS variants, a convertible was offered from 1958 until 1973. The Cabriolet d'Usine (factory convertible) were built by French carrossier Henri Chapron, for the Citroën dealer network. It was an expensive car, so only 1,365 were sold. These DS convertibles used a special frame which was reinforced on the sidemembers and rear suspension swingarm bearing box, similar to, but not identical to the Break (Station Wagon) frame.
CHAPRON VARIATIONS
In addition, Chapron also produced a few coupés, non-works convertibles and special sedans (including the "Prestige", same wheelbase but with a central divider, and the "Lorraine" notchback).
BOSSAERT COUPE
Between 1959 and 1964, Hector Bossaert produced a coupé on a DS chassis shortened by 470 mm. While the front end remained unchanged, the rear end featured notchback styling.
THE REACTOR
In 1965, noted American auto customizer Gene Winfield created The Reactor, a Citroën DS chassis, with a turbocharged 180 hp (130 kW) flat-six engine from the Corvair driving the front wheels. Since the DS already had the engine behind the front wheels, the longer engine meant only one row of seats. This was draped in a streamlined, low slung, aluminum body.
The Reactor was seen in American Television programs of the era, such as Star Trek: The Original Series episode 2.25 ("Bread and Circuses)," Batman episodes 110 ("Funny Feline Felonies") and 111 (driven by Catwoman Eartha Kitt), and Bewitched, which devoted its episode 3.19 ("Super Car") to The Reactor.
MICHELIN PLR
The Michelin PLR is a mobile tire evaluation machine, based on the DS Break, built in 1972, later used for promotion.
Technical details
SUSPENSION
In a hydropneumatic suspension system, each wheel is connected, not to a spring, but to a hydraulic suspension unit consisting of a hydraulic accumulator sphere of about 12 cm in diameter containing pressurised nitrogen, a cylinder containing hydraulic fluid screwed to the suspension sphere, a piston inside the cylinder connected by levers to the suspension itself, and a damper valve between the piston and the sphere. A membrane in the sphere prevented the nitrogen from escaping. The motion of the wheels translated to a motion of the piston, which acted on the oil in the nitrogen cushion and provided the spring effect. The damper valve took place of the shock absorber in conventional suspensions. The hydraulic cylinder was fed with hydraulic fluid from the main pressure reservoir via a height corrector, a valve controlled by the mid-position of the anti-roll bar connected to the axle. If the suspension was too low, the height corrector introduced high-pressure fluid; if it was too high, it released fluid back to the fluid reservoir. In this manner, a constant ride height was maintained. A control in the cabin allowed the driver to select one of five heights: normal riding height, two slightly higher riding heights for poor terrain, and two extreme positions for changing wheels. (The correct term, oleopneumatic (oil-air), has never gained widespread use. Hydropneumatic (water-air) continues to be preferred overwhelmingly.)
The DS did not have a jack for lifting the car off the ground. Instead, the hydraulic system enabled wheel changes with the aid of a simple adjustable stand. To change a flat tyre, one would adjust the suspension to its topmost setting, insert the stand into a special peg near the flat tyre, then readjust the suspension to its lowermost setting. The flat tyre would then retract upwards and hover above ground, ready to be changed. This system, used on the SM also, was superseded on the CX by a screw jack that, after the suspension was raised to the high position, lifted the tire clear of the ground. The DS system, while impressive to use, sometimes dropped the car quite suddenly, especially if the stand was not placed precisely or the ground was soft or unlevel.
SOURCE AND RESERVE OF PRESSURE
The central part of the hydraulic system was the high pressure pump, which maintained a pressure of between 130 and 150 bar in two accumulators. These accumulators were very similar in construction to the suspension spheres. One was dedicated to the front brakes, and the other ran the other hydraulic systems. (On the simpler ID models, the front brakes operated from the main accumulator.) Thus in case of a hydraulic failure, the first indication would be that the steering became heavy, followed by the gearbox not working; only later would the brakes fail.
Two different hydraulic pumps were used. The DS used a seven-cylinder axial piston pump driven off two belts and delivering 175 bar (2,540 psi) of pressure. The ID19, with its simpler hydraulic system, had a single-cylinder pump driven by an eccentric on the camshaft.
GEARBOX AND CLUTCH
HYDRAULIQUE OR CITROMATIC
The DS was initially offered only with the "hydraulique" four-speed semi-automatic (bvh—"boîte de vitesses hydraulique") gearbox.
This was a four-speed gearbox and clutch, operated by a hydraulic controller. To change gears, the driver flicked a lever behind the steering wheel to the next position and eased-up on the accelerator pedal. The hydraulic controller disengaged the clutch, engaged the nominated gear, and re-engaged the clutch. The speed of engagement of the clutch was controlled by a centrifugal regulator sensing engine rpm and driven off the camshaft by a belt, the position of the butterfly valve in the carburettor (i.e., the position of the accelerator), and the brake circuit. When the brake was pressed, the engine idle speed dropped to an rpm below the clutch engagement speed, thus preventing friction while stopped in gear at traffic lights. When the brake was released, the idle speed increased to the clutch dragging speed. The car would then creep forward much like automatic transmission cars. This drop in idle throttle position also caused the car to have more engine drag when the brakes were applied even before the car slowed to the idle speed in gear, preventing the engine from pulling against the brakes. In the event of loss of hydraulic pressure (following loss of system fluid), the clutch would disengage, to prevent driving, while brake pressure reserves would allow safe braking to standstill.
MANUAL - FOUR SPEED AND FIVE-SPEED
The later and simpler ID19 had the same gearbox and clutch, manually operated. This configuration was offered as a cheaper option for the DS in 1963. The mechanical aspects of the gearbox and clutch were completely conventional and the same elements were used in the ID 19. In September 1970, Citroën introduced a five-speed manual gearbox, in addition to the original four-speed unit.
FULLY AUTOMATIC
In September 1971 Citroën introduced a 3-speed fully automatic Borg-Warner 35 transmission gearbox, on the DS 21 and later DS 23 models. It is ironic that the fully automatic transmission DS was never sold in the US market, where this type of transmission had gained market share so quickly that it became the majority of the market by this time. Many automatic DSs, fuel-injected DS 23 sedans with air conditioning, were sold in Australia.
ENGINES
The DS was originally designed around an air-cooled flat-six based on the design of the 2-cylinder engine of the 2CV, similar to the motor in the Porsche 911. Technical and monetary problems forced this idea to be scrapped.
Thus, for such a modern car, the engine of the original DS 19 was also old-fashioned. It was derived from the engine of the 11CV Traction Avant (models 11B and 11C). It was an OHV four-cylinder engine with three main bearings and wet liners, and a bore of 78 mm and a stroke of 100 mm, giving a volumetric displacement of 1911 cc. The cylinder head had been reworked; the 11C had a reverse-flow cast iron cylinder head and generated 60 hp (45 kW) at 3800 rpm; by contrast, the DS 19 had an aluminium cross-flow head with hemispherical combustion chambers and generated 75 hp (56 kW) at 4500 rpm.
Like the Traction Avant, the DS had the gearbox mounted in front of the engine, with the differential in between. Thus some consider the DS to be a mid engine front-wheel drive car.
The DS and ID powerplants evolved throughout its 20-year production life. The car was underpowered and faced constant mechanical changes to boost the performance of the four-cylinder engine. The initial 1911 cc three main bearing engine (carried forward from the Traction Avant) of the DS 19 was replaced in 1965 with the 1985 cc five-bearing wet-cylinder motor, becoming the DS 19a (called DS 20 from September 1969).
The DS 21 was also introduced for model year 1965. This was a 2175 cc, five main bearing engine; power was 109 hp This engine received a substantial increase in power with the introduction of Bosch electronic fuel injection for 1970, making the DS one of the first mass-market cars to use electronic fuel injection. Power of the carbureted version also increased slightly at the same time, owing to the employment of larger inlet valves.
Lastly, 1973 saw the introduction of the 2347 cc engine of the DS 23 in both carbureted and fuel-injected forms. The DS 23 with electronic fuel injection was the most powerful production model, producing 141 hp (105 kW).
IDs and their variants went through a similar evolution, generally lagging the DS by about one year. ID saloon models never received the DS 23 engine or fuel injection, although the Break/Familiale versions received the carburetted version of the DS 23 engine when it was introduced, supplemented the DS20 Break/Familiale.
The top of the range ID model, The DSuper5 (DP) gained the DS21 engine (the only model that this engine was retained in) for the 1973 model year and it was mated to a five-speed gearbox. This should not be confused with the 1985 cc DSuper fitted with an optional "low ratio" five-speed gearbox, or with the previous DS21M (DJ) five-speed.
IN POPULAR CULTURE
President Charles de Gaulle survived an assassination attempt at Le Petit-Clamart near Paris on August 22, 1962, planned by Algerian War veteran Jean-Marie Bastien-Thiry. The plan was to ambush the motorcade with machine guns, disable the vehicles, and then close in for the kill. De Gaulle praised the unusual abilities of his unarmoured DS with saving his life – the car was peppered with bullets, and the shots had punctured the tyres, but the car could still escape at full speed. This event was accurately recreated in the 1973 film The Day of the Jackal.
Beyond de Gaulle and the French aristocracy, the roomy DS also appealed to French taxi drivers.
Outside France, the car drew an eclectic customer mix, such as Cosmonaut Yuri Gagarin, Pope John XXIII, painter Marc Chagall, and actors Ken Berry, Jeff Bridges, and Rosamund Pike.
The DS appeared in several episodes of contemporary television series Mission: Impossible, including substantial appearances in 'The Slave' (ep. 2.06) and 'Robot' (ep. 4.09).
An ode to Jane Child's DS21 appears on her 1989 self-titled album.
In 1989, the film Back to the Future Part II featured a modified Citroen DS as a flying taxicab, when the main characters travel 30 years into the future (2015). Scarface (1983 film) with Al Pacino and the 2009 television series The Mentalist both feature the DS in key roles. According to Internet Movie Cars Database, the DS/ID has made over 2,000 film and television appearances so far.
Two films focus on the DS, including The Goddess of 1967 about a Japanese man purchasing a DS (goddess or déesse in French) in Australia, and 1995's Icelandic-Japanese road movie Cold Fever.
LEGACY
Citroën DS values have been rising – a 1973 DS 23 Injection Electronique "Decapotable" (Chapron Convertible) sold for EUR €176,250 (USD $209,738) at Christie's Rétromobile in February 2006. and a similar car sold by Bonhams in February 2009 brought EUR €343,497 (USD $440,436). On 18 September 2009 a 1966 DS21 Decapotable Usine was sold by Bonhams for a hammer price of UK£131,300. Bonhams sold another DS21 Decapotable (1973) on 23 January 2010 for EUR €189,000.
The DS's beloved place in French society was demonstrated in Paris on 9 October 2005 with a celebration of the 50th anniversary of its launch. 1,600 DS cars drove in procession past the Arc de Triomphe.
From 2005 to 2008, a young Frenchman named Manuel Boileau travelled around the world in a 1971 DS ambulance. It was an 80,000 kilometer journey across 38 countries called Lunaya World Tour. While traveling through Laos, he located the forlorn 1974 DS Prestige belonging to Sisavang Vatthana, the last King of the Kingdom of Laos, which is now preserved and restored by specialists in Bangkok.
In 2009, Groupe PSA created a new brand - DS Automobiles, intended as high quality, high specification variations on existing models, with differing mechanics and bodywork. This brand ranges across four models, the DS3, DS4, DS5, and the China-only SUV DS 6. The DS3, launched in March 2010, is based on Citroen's new C3, but is more customisable and unique, bearing some resemblance to the original DS, with its "Shark Fin" side pillar. These have created their own niches, with the DS4 being a mix of a crossover and a coupe and the DS5 mixing a coupe and an estate. Many feature hybrid-diesel engines to maximise efficiency.
