Lately I have been building new trees and modifying old ones. Now the trees are planted on the side of a mountain I've been working on since late December. The mountain is constructed of 1" sheet styrofoam, paper "biscuits" wadded up from brown paper bags used to protect wine bottles, and plaster cloth. My mountain was designed to be removable for the ease of construction, maintenance of scenery, access to the tracks for cleaning and re-railing trains, and eventual moving.
On the lower slopes are Ponderosa Pines, then Quaking Aspens, Douglas Fir, and Engelmann Spruce. The latter trees are bottle-brush type trees from Heki that I've had for decades. All the others are from Woodland Scenics kits and components that I've modified to resemble the trees of northern New Mexico I'm not 100% satisfied with my attempt with aspens, but Woodland Scenics doesn't really have a tree armature shape or foliage color that suits me. My version of Ponderosa Pine and Douglas Fir is closer than most modelers' work. Bottle brush type trees are OK for certain firs and spruces with an overall conical shape but not for "pine" trees that too many modelers try to pass off.
On the right hand side of this view, you can see the cutout for my track, and the left side will butt up against the photo mural background. The pink styrofoam visible on the bottom is where the mountain drops into its slot. On the left front, part of the mountain overlaps onto the adjacent section, and a wide creek goes around the bend and disappears from view.
Today I fitted some bar ends on my singlespeed to see if they'd help with climbing. The bar ends went in-board of the brake levers on the North Road bars. It's a strange 'look', not unlike the expensive Surly Corner bar. A 15-mile road test went fine. Just need to rotate them upwards by a few degrees for more comfort.

Some background:
The Nakajima A6M2-N (Navy Type 2 Interceptor/Fighter-Bomber) was a single-crew floatplane. The Allied reporting name for the aircraft was 'Rufe'.
The A6M2-N floatplane was developed mainly to support amphibious operations and defend remote bases. It was based on the Mitsubishi A6M-2 Model 11 fuselage, with a modified tail and added floats. Despite the large central float and wing pontoons, the A6M2-N was aerodynamically a very clean aircraft: compared with its land-based A6M2 cousin, its performance degraded only by about 20%, and for a contemporary single engine floatplane its performance was outstanding.
The aircraft was deployed in 1942, referred to as the "Suisen 2" ("Hydro fighter type 2"), and intended for interceptor, fighter-bomber, and short reconnaissance support for amphibious landings, among other uses. However, when confronted with the first generation of Allied fighters, the A6M2-N was no match in aerial combat and rather employed in supportive roles.
Effectively, the A6M2-N was mostly utilized in defensive actions in the Aleutians and Solomon Islands operations. They were used with good efficiency against Allied positions: marking patrol elements, aiding warship guns, engaging convoys, and reconnoitering areas over-the-horizon.
The A6M2-Ns were also effective in harassing American PT boats at night, and they could drop flares to illuminate the PTs which were vulnerable to destroyer gunfire, and depended on cover of darkness. However, when Allied fighter coverage became more numerous and effective, the value of the A6M2-N dwindled and losses began to naturally mount.
In the Aleutian Campaign this fighter engaged with RCAF Curtiss P-40, Lockheed P-38 Lightning fighters and Boeing B-17 Flying Fortress bombers, but the A6M2-N inventory suffered a severe setback when, on August 7th, 1942, a seaplane base was destroyed by Allied fighter-bombers, taking with it most of the available A6M2-Ns stationed there.
The seaplane also served in defense of fueling depots in Balikpapan and Avon Bases (Dutch East Indies) and reinforced the Shumushu base (North Kuriles) in the same period.
Beyond their use from dispersed and improvised bases, A6M2-N fighters also served aboard seaplane carriers Kamikawa Maru in the Solomons and Kuriles areas and aboard Japanese raiders Hokoku Maru and Aikoku Maru in Indian Ocean raids.
Later in the conflict the Otsu Air Group utilized the A6M2-N as an interceptor alongside Kawanishi N1K1 Kyofu ('Rex') aircraft based in Biwa lake in the Honshū area, defending the Japanese home land against Allied raids.
A total of 327 were built, including the original prototype, before being halted in September 1943.
The last A6M2-N in military service was a single example recovered by the French forces in Indochina after the end of World War II. It crashed shortly after being overhauled, though.

The kit and its assembly:
This is a real world model, despite the weird looks (see below), and an entry for the Arawasi blog's "Japanese Aircraft Online Model Contest 005 - Japanese Seaplanes & Flying Boats" contest in summer 2017. Even though whifs were allowed to enter, I used the opportunity to build a kit I had originally bought for a few bucks and stashed away in the donor bank: a vintage LS Model Nakajima A6M2-N.
The mould dates back to 1963(!), and the kit was re-issued several times, also under the ARII label. You get a tiny box, with only two sprues moulded in a pale baby blue, and the number of parts is minimal. It's truly vintage and pretty toylike at first sight. Consequently, you have to face some real old-school issues, e. g. moulded markings for the roundels on the wings, general mediocre fit of anything and lots of sinkholes and flash. Then there are toylike solutions like the single-piece propeller or separate, moveable ailerons with bulging joints.
The cockpit interior is non-existent, too: there's just a blank place for a dashboard (to be cut out from the printed BW instructions!), and a spindly pilot figure which is held in mid air by some pins. Furthermore, the kit was designed to take a small electric motor in the nose (sold separately) to drive the propeller. Wires, as well as respective internal ducts, and an AA battery holder are included.
Sounds scary? Well, maybe, if you just build it OOB. But all these flaws should not keep the ambitious modeler away because the LS Model kit is (still) a sound basis to start from, even though and by today's standards, it is certainly not a match-winner for a rivet counter-esque competition.
For its age and the typical solutions of its time, it is actually surprisingly good: you get very fine engraved surface details (more delicate than many contemporary moulds!), a pretty thin, three-piece clear (yet blurry) canopy and, as a bonus to the elevons, separate flaps – a unique detail I have never come across before! Proportions are IMHO good, even though the cowling looks a bit fishy and the engravings are rather soft and shallow. Anyway, on the exterior, there’s anything you can ask for to be found, and as another bonus the kit comes with a beaching trolley, which makes display and diorama fitting easier.
Thanks to the kit's simplicity, the build in itself was pretty straightforward and simple. Cleaning the parts and checking fit was the biggest issue. Upon gluing the old styrene showed signs of serious reaction to the dissolving effect of modern glue: it took ages for the material to cure and become hard again for further work!? Weird…
The many sinkholes and overall displacements were corrected with some NC putty/PSR, the protruding elevon/flap joints sanded away as good as possible, and due to the wobbly nature of the kit’s styrene I added blobs of 2C putty inside of the wing halves as stabilizers.
Some mods and improvements were made, though. After cleaning the OOB propeller from tons of flash the piece turned out to be pretty usable, and it was put on a metal axis. A styrene tube adapter was added behind the relatively flat engine dummy, so that the prop can spin freely – for the later beauty pics, because no CG effect beats IMHO the real thing.
A cockpit interior was created from scratch and donor parts, using the new Airfix A6M model's cockpit as benchmark. It’s not an exact replica, because not much would later be visible, but I wanted, as a minimum, “something” inside. A better pilot figure was used, too, and strapped to the new seat with thin strips of adhesive masking tape as seatbelts.
Under the wings, the hardpoints were simulated with some bits of styrene and wire as shackles, but left empty Under the stabilizer fin I added a lug(?), made from thin wire, too.
The elevons were fixed in place, the seams to the wings filled with white glue in order to conceal the gaps as good as possible. The movable flaps remained, though, adding life to the model. The dolly was also taken more or less OOB, since it fits well. I just improved it with some sinkhole fillings and some other details, including cushions on the float stabilizers, made from paper tissue soaked with thinned white glue, and a towing bar.
Painting and markings:
The reason why I settled for an A6M2-N is mostly the weird paint scheme which can be applied, while still being a real world model: a lilac livery!
As far as I could find out, the A6M2-Ns initially carried an all-over IJN Grey livery, which was later, in late 1942, modified with dark green upper sides for a better concealment on the ground, and the Hinomaru received white edges for better contrast.
Anyway, during the Aleutian campaign and more or less in between these two major standards, several aircraft must have received a special camouflage with lilac upper surfaces, and this model depicts such a machine, based on various profiles but no color picture as reliable reference.
The sources I consulted, as well as pictures of finished A6M2-N models, show a wide variety of shades and paint scheme layouts, though. Upper colors range from pale pink through more or less bright shades of purple to a pale, rusty-reddish brown (maybe primer?), while the undersides show a wide range of greys or even light blue. Some depictions of Aleutian A6M2-Ns as profile or model even show a uniform wraparound scheme! Choice is yours, obviously...
Because of the corny information basis, I did my personal interpretation of the subject. I based my livery more or less on a profile by Michele Marsan, published in Aerei Modelismo Anno XII (March 1991). The unit information was taken from there, too – the only source that would provide such a reference.
My idea behind the livery and the eventual finish was that the machine once was fully painted in IJN Grey. Then, the violet upper color was added in the field (for whatever reason?), resulting in a slightly shaggy look and with the light grey shining through here and there in areas of higher wear, e. g. at the leading edges, cockpit area and some seams.
Painting started with an initial coat of aluminum under the floats, around the cockpit and on the leading edges. Then the undersides and some areas of the upper surfaces were painted with IJN grey. The latter is an individual mix of Humbrol 90 (Beige Green/RAF Sky) and a bit of 155 (Olive Drab, FS 34087). On top of that I added a thin primer layer of mauve (mix of ModelMaster’s Napoleonic Violet and Neutral Grey, Humbrol 176) on the still vacant upper surfaces – both as a preparation for the later weathering treatments (see below).
The following, basic lilac tone comes from Humbrol’s long-gone "Authentics" enamel line. The tin is probably 30 years old, but the content is still alive (and still has a distinctive, sour stench…)! I cannot identify the tone anymore with certainty, but I guess that it is 'HJ 4: Mauve N 9', one of the line’s Japanese WWII tones which was later not carried over to the standard tones, still available today.
Anyway, the color is a dull, rather greyish violet, relatively dark (a bit like RAF Ocean Grey), and it fits well as a camouflage tone on this specific model. Since there’s no better alternative I could think of except for an individual mix or garish, off-the-rack pop art tones, I went with it.
After overall basic painting was done and thoroughly cured, weathering started with a careful wet sand paper treatment, removing the salt grain masks and revealing some of the lower IJN Grey and aluminum layers. While this appears messy, I found that the result looks more realistic than artificial weathering applied as paint effects on top of the basic paint.
The engine cowling was painted separately, with a mix of black and a little dark blue. The propeller received an aluminum spinner (Humbrol’s Matt Aluminum Metallizer), while the blades received aluminum front sides (Revell acrylics), and red brown (Humbrol 160) back sides. Two thin, red stripes decorate the propeller tips (Decals, left over from an AZ Model Ki-78, IIRC).
As a standard procedure, the kit received a light wash with thinned black ink, revealing the engraved panel lines, plus some post-shading in order to emphasize panels and add visual contrast and ‘drama’.
Decals and markings were improvised and come from the spares box, since I did not trust the vintage OOB decals - even though they are in so far nice that the sheet contains any major marking as well as a full set of letter so that an individual tail code could be created. Anyway, the model's real world benchmark did not carry any numeric or letter code, just Hinomaru in standard positions and a horizontal, white-and-red stripe on the fin.
The roundels actually belong to a JSDAF F-4EJ, some stencils come from a leftover Hobby Boss A6M sheet. The fin decoration was created with generic decal sheet material (TL Modellbau). Similar stuff was also used for the markings on the central float, as well as for the yellow ID markings on the inner wings' leading edges. I am just not certain whether the real aircraft carried them at all? But they were introduced with the new green upper surfaces in late 1942, so that they appear at least plausible. Another argument in this marking‘s favor is that it simply adds even more color to the model!
The cockpit interior was painted in a light khaki tone (a mix of Humbrol 159 and 94), while the flaps' interior was painted with Aodake Iro (an individual mix of acrylic aluminum and translucent teal paint). Lacking good reference material, the beaching trolley became IJA Green, with some good weathering with dry-brushed silver on the edges and traces of rust here and there (the latter created with artist acrylics.
Close to the (literal) finish line, some soot and oil stains were added with graphite and Tamiya's 'Smoke', and the kit finally received a coat of matt acrylic varnish (Italeri); to the varnish on the engine cover a bit of gloss varnish was added, for a sheen finish.
In the end, quite a challenging build. Not a winner, but …different. Concerning the LS Model kit as such, I must say that - despite its age of more than 50 years now - the A6M2-N model is still a worthwhile offer, if you invest some effort. Sure, there are certainly better 1:72 options available (e. g. the Hasegawa kit, its mould was created in 1995 and should be light years ahead concerning detail and fit. Not certain about the Revell/Frog and Jo-Han alternatives, though), but tackling this simple, vintage kit was fun in itself. And, based on what you get out of the little box, the result is not bad at all!
Beyond the technical aspects, I am also pleased with the visual result of the build. At first glance, this antiquity looks pretty convincing. And the disputable, strange lilac tone really makes this A6M2-N model …outstanding. Even though I still wonder what might have been the rationale behind this tone? The only thing I could imagine is a dedicated scheme for missions at dusk/dawn, similar to the pink RAF recce Spitfires in early WWII? It would be plausible, though, since the A6M2-Ns were tasked with nocturnal reconnoitre and ground attack missions.

I always wanna make a Hong Kong building on fire diorama, finally I have done it! This diorama is relatively small, it is only (12Wx16Lx15H)cm, but it is a very busy diorama with lots of action happening.
This is a frictional diorama not based on actual scene. The scratch-built tenement building is based on common 1960-70s style residential buildings. Also the pedestrian flyover is based on a typical Hong Kong's style flyover.
The smoke was made of cotton, and the fire in the apartment was created by Daiso's LED candle lamp.
All vehicles are Hong Kong's '80M Bus Model shop' models but I further weathered and highlighted them by applying layers of brown & black wash. There are only two types of fire truck available from 80M, the Hydraulic Platform (white ladder) and the Turnable Ladder (highest silver ladder) respectively, therefore the fire major pump truck (far left, the one under the pedestrian bridge) was created by modifying a spare hydraulic platform truck model by a bit of scratch-building & repainting.
The policemen & firefighters are Tomytec figures that repainted to Hong Kong's uniform colours. They were all applied with layers of brown wash for high-lighting.
I added various details to make the scene as realistic as to an actual fire scene as much as possible, by adding the water pipes laid on the street by firemen which is common in a fire fighting scene. I also added some water on the street to show water spill from trucks & pipes. Burned debris dropped on the street directly under the burning apartment are also added.

Spiders (order Araneae) are air-breathing arthropods that have eight legs and chelicerae with fangs that inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all other orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every habitat with the exceptions of air and sea colonization. As of November 2015, at least 45,700 spider species, and 114 families have been recorded by taxonomists. However, there has been dissension within the scientific community as to how all these families should be classified, as evidenced by the over 20 different classifications that have been proposed since 1900.
Anatomically, spiders differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax and abdomen, and joined by a small, cylindrical pedicel. Unlike insects, spiders do not have antennae. In all except the most primitive group, the Mesothelae, spiders have the most centralized nervous systems of all arthropods, as all their ganglia are fused into one mass in the cephalothorax. Unlike most arthropods, spiders have no extensor muscles in their limbs and instead extend them by hydraulic pressure.
Their abdomens bear appendages that have been modified into spinnerets that extrude silk from up to six types of glands. Spider webs vary widely in size, shape and the amount of sticky thread used. It now appears that the spiral orb web may be one of the earliest forms, and spiders that produce tangled cobwebs are more abundant and diverse than orb-web spiders. Spider-like arachnids with silk-producing spigots appeared in the Devonian period about 386 million years ago, but these animals apparently lacked spinnerets. True spiders have been found in Carboniferous rocks from 318 to 299 million years ago, and are very similar to the most primitive surviving suborder, the Mesothelae. The main groups of modern spiders, Mygalomorphae and Araneomorphae, first appeared in the Triassic period, before 200 million years ago.
A herbivorous species, Bagheera kiplingi, was described in 2008,[5] but all other known species are predators, mostly preying on insects and on other spiders, although a few large species also take birds and lizards. Spiders use a wide range of strategies to capture prey: trapping it in sticky webs, lassoing it with sticky bolas, mimicking the prey to avoid detection, or running it down. Most detect prey mainly by sensing vibrations, but the active hunters have acute vision, and hunters of the genus Portia show signs of intelligence in their choice of tactics and ability to develop new ones. Spiders' guts are too narrow to take solids, and they liquefy their food by flooding it with digestive enzymes and grinding it with the bases of their pedipalps, as they do not have true jaws.
Male spiders identify themselves by a variety of complex courtship rituals to avoid being eaten by the females. Males of most species survive a few matings, limited mainly by their short life spans. Females weave silk egg-cases, each of which may contain hundreds of eggs. Females of many species care for their young, for example by carrying them around or by sharing food with them. A minority of species are social, building communal webs that may house anywhere from a few to 50,000 individuals. Social behavior ranges from precarious toleration, as in the widow spiders, to co-operative hunting and food-sharing. Although most spiders live for at most two years, tarantulas and other mygalomorph spiders can live up to 25 years in captivity.
While the venom of a few species is dangerous to humans, scientists are now researching the use of spider venom in medicine and as non-polluting pesticides. Spider silk provides a combination of lightness, strength and elasticity that is superior to that of synthetic materials, and spider silk genes have been inserted into mammals and plants to see if these can be used as silk factories. As a result of their wide range of behaviors, spiders have become common symbols in art and mythology symbolizing various combinations of patience, cruelty and creative powers. An abnormal fear of spiders is called arachnophobia.
BODY PLAN
Spiders are chelicerates and therefore arthropods.[6] As arthropods they have: segmented bodies with jointed limbs, all covered in a cuticle made of chitin and proteins; heads that are composed of several segments that fuse during the development of the embryo. Being chelicerates, their bodies consist of two tagmata, sets of segments that serve similar functions: the foremost one, called the cephalothorax or prosoma, is a complete fusion of the segments that in an insect would form two separate tagmata, the head and thorax; the rear tagma is called the abdomen or opisthosoma. In spiders, the cephalothorax and abdomen are connected by a small cylindrical section, the pedicel. The pattern of segment fusion that forms chelicerates' heads is unique among arthropods, and what would normally be the first head segment disappears at an early stage of development, so that chelicerates lack the antennae typical of most arthropods. In fact, chelicerates' only appendages ahead of the mouth are a pair of chelicerae, and they lack anything that would function directly as "jaws". The first appendages behind the mouth are called pedipalps, and serve different functions within different groups of chelicerates.
Spiders and scorpions are members of one chelicerate group, the arachnids. Scorpions' chelicerae have three sections and are used in feeding. Spiders' chelicerae have two sections and terminate in fangs that are generally venomous, and fold away behind the upper sections while not in use. The upper sections generally have thick "beards" that filter solid lumps out of their food, as spiders can take only liquid food.[8] Scorpions' pedipalps generally form large claws for capturing prey, while those of spiders are fairly small appendages whose bases also act as an extension of the mouth; in addition, those of male spiders have enlarged last sections used for sperm transfer.
In spiders, the cephalothorax and abdomen are joined by a small, cylindrical pedicel, which enables the abdomen to move independently when producing silk. The upper surface of the cephalothorax is covered by a single, convex carapace, while the underside is covered by two rather flat plates. The abdomen is soft and egg-shaped. It shows no sign of segmentation, except that the primitive Mesothelae, whose living members are the Liphistiidae, have segmented plates on the upper surface.
CIRCULATION AND RESPIRATION
Like other arthropods, spiders are coelomates in which the coelom is reduced to small areas round the reproductive and excretory systems. Its place is largely taken by a hemocoel, a cavity that runs most of the length of the body and through which blood flows. The heart is a tube in the upper part of the body, with a few ostia that act as non-return valves allowing blood to enter the heart from the hemocoel but prevent it from leaving before it reaches the front end. However, in spiders, it occupies only the upper part of the abdomen, and blood is discharged into the hemocoel by one artery that opens at the rear end of the abdomen and by branching arteries that pass through the pedicle and open into several parts of the cephalothorax. Hence spiders have open circulatory systems. The blood of many spiders that have book lungs contains the respiratory pigment hemocyanin to make oxygen transport more efficient.
Spiders have developed several different respiratory anatomies, based on book lungs, a tracheal system, or both. Mygalomorph and Mesothelae spiders have two pairs of book lungs filled with haemolymph, where openings on the ventral surface of the abdomen allow air to enter and diffuse oxygen. This is also the case for some basal araneomorph spiders, like the family Hypochilidae, but the remaining members of this group have just the anterior pair of book lungs intact while the posterior pair of breathing organs are partly or fully modified into tracheae, through which oxygen is diffused into the haemolymph or directly to the tissue and organs. The trachea system has most likely evolved in small ancestors to help resist desiccation. The trachea were originally connected to the surroundings through a pair of openings called spiracles, but in the majority of spiders this pair of spiracles has fused into a single one in the middle, and moved backwards close to the spinnerets. Spiders that have tracheae generally have higher metabolic rates and better water conservation. Spiders are ectotherms, so environmental temperatures affect their activity.
FEEDING, DIGESTION AND EXCRETION
Uniquely among chelicerates, the final sections of spiders' chelicerae are fangs, and the great majority of spiders can use them to inject venom into prey from venom glands in the roots of the chelicerae. The family Uloboridae has lost its venom glands, and kills its prey with silk instead. Like most arachnids, including scorpions, spiders have a narrow gut that can only cope with liquid food and spiders have two sets of filters to keep solids out. They use one of two different systems of external digestion. Some pump digestive enzymes from the midgut into the prey and then suck the liquified tissues of the prey into the gut, eventually leaving behind the empty husk of the prey. Others grind the prey to pulp using the chelicerae and the bases of the pedipalps, while flooding it with enzymes; in these species, the chelicerae and the bases of the pedipalps form a preoral cavity that holds the food they are processing.
The stomach in the cephalothorax acts as a pump that sends the food deeper into the digestive system. The mid gut bears many digestive ceca, compartments with no other exit, that extract nutrients from the food; most are in the abdomen, which is dominated by the digestive system, but a few are found in the cephalothorax.
Most spiders convert nitrogenous waste products into uric acid, which can be excreted as a dry material. Malphigian tubules ("little tubes") extract these wastes from the blood in the hemocoel and dump them into the cloacal chamber, from which they are expelled through the anus. Production of uric acid and its removal via Malphigian tubules are a water-conserving feature that has evolved independently in several arthropod lineages that can live far away from water, for example the tubules of insects and arachnids develop from completely different parts of the embryo. However, a few primitive spiders, the sub-order Mesothelae and infra-order Mygalomorphae, retain the ancestral arthropod nephridia ("little kidneys"), which use large amounts of water to excrete nitrogenous waste products as ammonia.
CENTRAL NERVOUS SYSTEM
The basic arthropod central nervous system consists of a pair of nerve cords running below the gut, with paired ganglia as local control centers in all segments; a brain formed by fusion of the ganglia for the head segments ahead of and behind the mouth, so that the esophagus is encircled by this conglomeration of ganglia. Except for the primitive Mesothelae, of which the Liphistiidae are the sole surviving family, spiders have the much more centralized nervous system that is typical of arachnids: all the ganglia of all segments behind the esophagus are fused, so that the cephalothorax is largely filled with nervous tissue and there are no ganglia in the abdomen; in the Mesothelae, the ganglia of the abdomen and the rear part of the cephalothorax remain unfused.
Despite the relatively small central nervous system, some spiders (like Portia) exhibit complex behaviour, including the ability to use a trial-and-error approach.
Sense organs
EYES
Most spiders have four pairs of eyes on the top-front area of the cephalothorax, arranged in patterns that vary from one family to another. The pair at the front are of the type called pigment-cup ocelli ("little eyes"), which in most arthropods are only capable of detecting the direction from which light is coming, using the shadow cast by the walls of the cup. However, the main eyes at the front of spiders' heads are pigment-cup ocelli that are capable of forming images. The other eyes are thought to be derived from the compound eyes of the ancestral chelicerates, but no longer have the separate facets typical of compound eyes. Unlike the main eyes, in many spiders these secondary eyes detect light reflected from a reflective tapetum lucidum, and wolf spiders can be spotted by torch light reflected from the tapeta. On the other hand, jumping spiders' secondary eyes have no tapeta. Some jumping spiders' visual acuity exceeds by a factor of ten that of dragonflies, which have by far the best vision among insects; in fact the human eye is only about five times sharper than a jumping spider's. They achieve this by a telephoto-like series of lenses, a four-layer retina and the ability to swivel their eyes and integrate images from different stages in the scan. The downside is that the scanning and integrating processes are relatively slow.
There are spiders with a reduced number of eyes, of these those with six-eyes are the most numerous and are missing a pair of eyes on the anterior median line, others species have four-eyes and some just two. Cave dwelling species have no eyes, or possess vestigial eyes incapable of sight.
OTHER SENSES
As with other arthropods, spiders' cuticles would block out information about the outside world, except that they are penetrated by many sensors or connections from sensors to the nervous system. In fact, spiders and other arthropods have modified their cuticles into elaborate arrays of sensors. Various touch sensors, mostly bristles called setae, respond to different levels of force, from strong contact to very weak air currents. Chemical sensors provide equivalents of taste and smell, often by means of setae. Pedipalps carry a large number of such setae sensitive to contact chemicals and air-borne smells, such as female pheromones. Spiders also have in the joints of their limbs slit sensillae that detect forces and vibrations. In web-building spiders, all these mechanical and chemical sensors are more important than the eyes, while the eyes are most important to spiders that hunt actively.
Like most arthropods, spiders lack balance and acceleration sensors and rely on their eyes to tell them which way is up. Arthropods' proprioceptors, sensors that report the force exerted by muscles and the degree of bending in the body and joints, are well understood. On the other hand, little is known about what other internal sensors spiders or other arthropods may have.
LOCMOTION
Each of the eight legs of a spider consists of seven distinct parts. The part closest to and attaching the leg to the cephalothorax is the coxa; the next segment is the short trochanter that works as a hinge for the following long segment, the femur; next is the spider's knee, the patella, which acts as the hinge for the tibia; the metatarsus is next, and it connects the tibia to the tarsus (which may be thought of as a foot of sorts); the tarsus ends in a claw made up of either two or three points, depending on the family to which the spider belongs. Although all arthropods use muscles attached to the inside of the exoskeleton to flex their limbs, spiders and a few other groups still use hydraulic pressure to extend them, a system inherited from their pre-arthropod ancestors. The only extensor muscles in spider legs are located in the three hip joints (bordering the coxa and the trochanter). As a result, a spider with a punctured cephalothorax cannot extend its legs, and the legs of dead spiders curl up. Spiders can generate pressures up to eight times their resting level to extend their legs, and jumping spiders can jump up to 50 times their own length by suddenly increasing the blood pressure in the third or fourth pair of legs. Although larger spiders use hydraulics to straighten their legs, unlike smaller jumping spiders they depend on their flexor muscles to generate the propulsive force for their jumps.
Most spiders that hunt actively, rather than relying on webs, have dense tufts of fine hairs between the paired claws at the tips of their legs. These tufts, known as scopulae, consist of bristles whose ends are split into as many as 1,000 branches, and enable spiders with scopulae to walk up vertical glass and upside down on ceilings. It appears that scopulae get their grip from contact with extremely thin layers of water on surfaces.[8] Spiders, like most other arachnids, keep at least four legs on the surface while walking or running.
SILK PRODUCTION
The abdomen has no appendages except those that have been modified to form one to four (usually three) pairs of short, movable spinnerets, which emit silk. Each spinneret has many spigots, each of which is connected to one silk gland. There are at least six types of silk gland, each producing a different type of silk.
Silk is mainly composed of a protein very similar to that used in insect silk. It is initially a liquid, and hardens not by exposure to air but as a result of being drawn out, which changes the internal structure of the protein. It is similar in tensile strength to nylon and biological materials such as chitin, collagen and cellulose, but is much more elastic. In other words, it can stretch much further before breaking or losing shape.
Some spiders have a cribellum, a modified spinneret with up to 40,000 spigots, each of which produces a single very fine fiber. The fibers are pulled out by the calamistrum, a comb-like set of bristles on the jointed tip of the cribellum, and combined into a composite woolly thread that is very effective in snagging the bristles of insects. The earliest spiders had cribella, which produced the first silk capable of capturing insects, before spiders developed silk coated with sticky droplets. However, most modern groups of spiders have lost the cribellum.
Tarantulas also have silk glands in their feet.
Even species that do not build webs to catch prey use silk in several ways: as wrappers for sperm and for fertilized eggs; as a "safety rope"; for nest-building; and as "parachutes" by the young of some species.
REPRODUCTION AND LIFE CYCLE
Spiders reproduce sexually and fertilization is internal but indirect, in other words the sperm is not inserted into the female's body by the male's genitals but by an intermediate stage. Unlike many land-living arthropods, male spiders do not produce ready-made spermatophores (packages of sperm), but spin small sperm webs on to which they ejaculate and then transfer the sperm to special syringe-like structures, palpal bulbs or palpal organs, borne on the tips of the pedipalps of mature males. When a male detects signs of a female nearby he checks whether she is of the same species and whether she is ready to mate; for example in species that produce webs or "safety ropes", the male can identify the species and sex of these objects by "smell".
Spiders generally use elaborate courtship rituals to prevent the large females from eating the small males before fertilization, except where the male is so much smaller that he is not worth eating. In web-weaving species, precise patterns of vibrations in the web are a major part of the rituals, while patterns of touches on the female's body are important in many spiders that hunt actively, and may "hypnotize" the female. Gestures and dances by the male are important for jumping spiders, which have excellent eyesight. If courtship is successful, the male injects his sperm from the palpal bulbs into the female's genital opening, known as the epigyne, on the underside of her abdomen. Female's reproductive tracts vary from simple tubes to systems that include seminal receptacles in which females store sperm and release it when they are ready.
Males of the genus Tidarren amputate one of their palps before maturation and enter adult life with one palp only. The palps are 20% of male's body mass in this species, and detaching one of the two improves mobility. In the Yemeni species Tidarren argo, the remaining palp is then torn off by the female. The separated palp remains attached to the female's epigynum for about four hours and apparently continues to function independently. In the meantime, the female feeds on the palpless male. In over 60% of cases, the female of the Australian redback spider kills and eats the male after it inserts its second palp into the female's genital opening; in fact, the males co-operate by trying to impale themselves on the females' fangs. Observation shows that most male redbacks never get an opportunity to mate, and the "lucky" ones increase the likely number of offspring by ensuring that the females are well-fed. However, males of most species survive a few matings, limited mainly by their short life spans. Some even live for a while in their mates' webs.
Females lay up to 3,000 eggs in one or more silk egg sacs, which maintain a fairly constant humidity level. In some species, the females die afterwards, but females of other species protect the sacs by attaching them to their webs, hiding them in nests, carrying them in the chelicerae or attaching them to the spinnerets and dragging them along.
Baby spiders pass all their larval stages inside the egg and hatch as spiderlings, very small and sexually immature but similar in shape to adults. Some spiders care for their young, for example a wolf spider's brood cling to rough bristles on the mother's back, and females of some species respond to the "begging" behaviour of their young by giving them their prey, provided it is no longer struggling, or even regurgitate food.
Like other arthropods, spiders have to molt to grow as their cuticle ("skin") cannot stretch. In some species males mate with newly molted females, which are too weak to be dangerous to the males. Most spiders live for only one to two years, although some tarantulas can live in captivity for over 20 years.
SIZE
Spiders occur in a large range of sizes. The smallest, Patu digua from Colombia, are less than 0.37 mm in body length. The largest and heaviest spiders occur among tarantulas, which can have body lengths up to 90 mm and leg spans up to 250 mm.
COLORATION
Only three classes of pigment (ommochromes, bilins and guanine) have been identified in spiders, although other pigments have been detected but not yet characterized. Melanins, carotenoids and pterins, very common in other animals, are apparently absent. In some species, the exocuticle of the legs and prosoma is modified by a tanning process, resulting in brown coloration. Bilins are found, for example, in Micrommata virescens, resulting in its green color. Guanine is responsible for the white markings of the European garden spider Araneus diadematus. It is in many species accumulated in specialized cells called guanocytes. In genera such as Tetragnatha, Leucauge, Argyrodes or Theridiosoma, guanine creates their silvery appearance. While guanine is originally an end-product of protein metabolism, its excretion can be blocked in spiders, leading to an increase in its storage. Structural colors occur in some species, which are the result of the diffraction, scattering or interference of light, for example by modified setae or scales. The white prosoma of Argiope results from hairs reflecting the light, Lycosa and Josa both have areas of modified cuticle that act as light reflectors.
ECOGOGY AND BEHAVIOR
NON-PREDATORY FEEDING
Although spiders are generally regarded as predatory, the jumping spider Bagheera kiplingi gets over 90% of its food from fairly solid plant material produced by acacias as part of a mutually beneficial relationship with a species of ant.
Juveniles of some spiders in the families Anyphaenidae, Corinnidae, Clubionidae, Thomisidae and Salticidae feed on plant nectar. Laboratory studies show that they do so deliberately and over extended periods, and periodically clean themselves while feeding. These spiders also prefer sugar solutions to plain water, which indicates that they are seeking nutrients. Since many spiders are nocturnal, the extent of nectar consumption by spiders may have been underestimated. Nectar contains amino acids, lipids, vitamins and minerals in addition to sugars, and studies have shown that other spider species live longer when nectar is available. Feeding on nectar avoids the risks of struggles with prey, and the costs of producing venom and digestive enzymes.
Various species are known to feed on dead arthropods (scavenging), web silk, and their own shed exoskeletons. Pollen caught in webs may also be eaten, and studies have shown that young spiders have a better chance of survival if they have the opportunity to eat pollen. In captivity, several spider species are also known to feed on bananas, marmalade, milk, egg yolk and sausages.
METHODS OF CAPTURING PREY
The best-known method of prey capture is by means of sticky webs. Varying placement of webs allows different species of spider to trap different insects in the same area, for example flat horizontal webs trap insects that fly up from vegetation underneath while flat vertical webs trap insects in horizontal flight. Web-building spiders have poor vision, but are extremely sensitive to vibrations.
Females of the water spider Argyroneta aquatica build underwater "diving bell" webs that they fill with air and use for digesting prey, molting, mating and raising offspring. They live almost entirely within the bells, darting out to catch prey animals that touch the bell or the threads that anchor it. A few spiders use the surfaces of lakes and ponds as "webs", detecting trapped insects by the vibrations that these cause while struggling.
Net-casting spiders weave only small webs, but then manipulate them to trap prey. Those of the genus Hyptiotes and the family Theridiosomatidae stretch their webs and then release them when prey strike them, but do not actively move their webs. Those of the family Deinopidae weave even smaller webs, hold them outstretched between their first two pairs of legs, and lunge and push the webs as much as twice their own body length to trap prey, and this move may increase the webs' area by a factor of up to ten. Experiments have shown that Deinopis spinosus has two different techniques for trapping prey: backwards strikes to catch flying insects, whose vibrations it detects; and forward strikes to catch ground-walking prey that it sees. These two techniques have also been observed in other deinopids. Walking insects form most of the prey of most deinopids, but one population of Deinopis subrufa appears to live mainly on tipulid flies that they catch with the backwards strike.
Mature female bolas spiders of the genus Mastophora build "webs" that consist of only a single "trapeze line", which they patrol. They also construct a bolas made of a single thread, tipped with a large ball of very wet sticky silk. They emit chemicals that resemble the pheromones of moths, and then swing the bolas at the moths. Although they miss on about 50% of strikes, they catch about the same weight of insects per night as web-weaving spiders of similar size. The spiders eat the bolas if they have not made a kill in about 30 minutes, rest for a while, and then make new bolas. Juveniles and adult males are much smaller and do not make bolas. Instead they release different pheromones that attract moth flies, and catch them with their front pairs of legs.
The primitive Liphistiidae, the "trapdoor spiders" of the family Ctenizidae and many tarantulas are ambush predators that lurk in burrows, often closed by trapdoors and often surrounded by networks of silk threads that alert these spiders to the presence of prey. Other ambush predators do without such aids, including many crab spiders, and a few species that prey on bees, which see ultraviolet, can adjust their ultraviolet reflectance to match the flowers in which they are lurking. Wolf spiders, jumping spiders, fishing spiders and some crab spiders capture prey by chasing it, and rely mainly on vision to locate prey.Some jumping spiders of the genus Portia hunt other spiders in ways that seem intelligent, outflanking their victims or luring them from their webs. Laboratory studies show that Portia's instinctive tactics are only starting points for a trial-and-error approach from which these spiders learn very quickly how to overcome new prey species. However, they seem to be relatively slow "thinkers", which is not surprising, as their brains are vastly smaller than those of mammalian predators.Ant-mimicking spiders face several challenges: they generally develop slimmer abdomens and false "waists" in the cephalothorax to mimic the three distinct regions (tagmata) of an ant's body; they wave the first pair of legs in front of their heads to mimic antennae, which spiders lack, and to conceal the fact that they have eight legs rather than six; they develop large color patches round one pair of eyes to disguise the fact that they generally have eight simple eyes, while ants have two compound eyes; they cover their bodies with reflective hairs to resemble the shiny bodies of ants. In some spider species, males and females mimic different ant species, as female spiders are usually much larger than males. Ant-mimicking spiders also modify their behavior to resemble that of the target species of ant; for example, many adopt a zig-zag pattern of movement, ant-mimicking jumping spiders avoid jumping, and spiders of the genus Synemosyna walk on the outer edges of leaves in the same way as Pseudomyrmex. Ant-mimicry in many spiders and other arthropods may be for protection from predators that hunt by sight, including birds, lizards and spiders. However, several ant-mimicking spiders prey either on ants or on the ants' "livestock", such as aphids. When at rest, the ant-mimicking crab spider Amyciaea does not closely resemble Oecophylla, but while hunting it imitates the behavior of a dying ant to attract worker ants. After a kill, some ant-mimicking spiders hold their victims between themselves and large groups of ants to avoid being attacked.
DEFENSE
There is strong evidence that spiders' coloration is camouflage that helps them to evade their major predators, birds and parasitic wasps, both of which have good color vision. Many spider species are colored so as to merge with their most common backgrounds, and some have disruptive coloration, stripes and blotches that break up their outlines. In a few species, such as the Hawaiian happy-face spider, Theridion grallator, several coloration schemes are present in a ratio that appears to remain constant, and this may make it more difficult for predators to recognize the species. Most spiders are insufficiently dangerous or unpleasant-tasting for warning coloration to offer much benefit. However, a few species with powerful venoms, large jaws or irritant hairs have patches of warning colors, and some actively display these colors when threatened.
Many of the family Theraphosidae, which includes tarantulas and baboon spiders, have urticating hairs on their abdomens and use their legs to flick them at attackers. These hairs are fine setae (bristles) with fragile bases and a row of barbs on the tip. The barbs cause intense irritation but there is no evidence that they carry any kind of venom. A few defend themselves against wasps by including networks of very robust threads in their webs, giving the spider time to flee while the wasps are struggling with the obstacles. The golden wheeling spider, Carparachne aureoflava, of the Namibian desert escapes parasitic wasps by flipping onto its side and cartwheeling down sand dunes.
SOCIAL SPIDERS
A few spider species that build webs live together in large colonies and show social behavior, although not as complex as in social insects. Anelosimus eximius (in the family Theridiidae) can form colonies of up to 50,000 individuals. The genus Anelosimus has a strong tendency towards sociality: all known American species are social, and species in Madagascar are at least somewhat social. Members of other species in the same family but several different genera have independently developed social behavior. For example, although Theridion nigroannulatum belongs to a genus with no other social species, T. nigroannulatum build colonies that may contain several thousand individuals that co-operate in prey capture and share food. Other communal spiders include several Philoponella species (family Uloboridae), Agelena consociata (family Agelenidae) and Mallos gregalis (family Dictynidae). Social predatory spiders need to defend their prey against kleptoparasites ("thieves"), and larger colonies are more successful in this. The herbivorous spider Bagheera kiplingi lives in small colonies which help to protect eggs and spiderlings. Even widow spiders (genus Latrodectus), which are notoriously cannibalistic, have formed small colonies in captivity, sharing webs and feeding together.
WEB TYPES
There is no consistent relationship between the classification of spiders and the types of web they build: species in the same genus may build very similar or significantly different webs. Nor is there much correspondence between spiders' classification and the chemical composition of their silks. Convergent evolution in web construction, in other words use of similar techniques by remotely related species, is rampant. Orb web designs and the spinning behaviors that produce them are the best understood. The basic radial-then-spiral sequence visible in orb webs and the sense of direction required to build them may have been inherited from the common ancestors of most spider groups. However, the majority of spiders build non-orb webs. It used to be thought that the sticky orb web was an evolutionary innovation resulting in the diversification of the Orbiculariae. Now, however, it appears that non-orb spiders are a sub-group that evolved from orb-web spiders, and non-orb spiders have over 40% more species and are four times as abundant as orb-web spiders. Their greater success may be because sphecid wasps, which are often the dominant predators of spiders, much prefer to attack spiders that have flat webs.
ORB WEBS
About half the potential prey that hit orb webs escape. A web has to perform three functions: intercepting the prey (intersection), absorbing its momentum without breaking (stopping), and trapping the prey by entangling it or sticking to it (retention). No single design is best for all prey. For example: wider spacing of lines will increase the web's area and hence its ability to intercept prey, but reduce its stopping power and retention; closer spacing, larger sticky droplets and thicker lines would improve retention, but would make it easier for potential prey to see and avoid the web, at least during the day. However, there are no consistent differences between orb webs built for use during the day and those built for use at night. In fact, there is no simple relationship between orb web design features and the prey they capture, as each orb-weaving species takes a wide range of prey.
The hubs of orb webs, where the spiders lurk, are usually above the center, as the spiders can move downwards faster than upwards. If there is an obvious direction in which the spider can retreat to avoid its own predators, the hub is usually offset towards that direction.
Horizontal orb webs are fairly common, despite being less effective at intercepting and retaining prey and more vulnerable to damage by rain and falling debris. Various researchers have suggested that horizontal webs offer compensating advantages, such as reduced vulnerability to wind damage; reduced visibility to prey flying upwards, because of the back-lighting from the sky; enabling oscillations to catch insects in slow horizontal flight. However, there is no single explanation for the common use of horizontal orb webs.
Spiders often attach highly visible silk bands, called decorations or stabilimenta, to their webs. Field research suggests that webs with more decorative bands captured more prey per hour. However, a laboratory study showed that spiders reduce the building of these decorations if they sense the presence of predators.
There are several unusual variants of orb web, many of them convergently evolved, including: attachment of lines to the surface of water, possibly to trap insects in or on the surface; webs with twigs through their centers, possibly to hide the spiders from predators; "ladder-like" webs that appear most effective in catching moths. However, the significance of many variations is unclear.
In 1973, Skylab 3 took two orb-web spiders into space to test their web-spinning capabilities in zero gravity. At first, both produced rather sloppy webs, but they adapted quickly.
TANGLEWEB SPIDERS (COBWEB SPIDERS)
Members of the family Theridiidae weave irregular, tangled, three-dimensional webs, popularly known as cobwebs. There seems to be an evolutionary trend towards a reduction in the amount of sticky silk used, leading to its total absence in some species. The construction of cobwebs is less stereotyped than that of orb-webs, and may take several days.
OTHER TYPES OF WEBS
The Linyphiidae generally make horizontal but uneven sheets, with tangles of stopping threads above. Insects that hit the stopping threads fall onto the sheet or are shaken onto it by the spider, and are held by sticky threads on the sheet until the spider can attack from below.
EVOLUTION
FOSSIL RECORD
Although the fossil record of spiders is considered poor, almost 1000 species have been described from fossils. Because spiders' bodies are quite soft, the vast majority of fossil spiders have been found preserved in amber. The oldest known amber that contains fossil arthropods dates from 130 million years ago in the Early Cretaceous period. In addition to preserving spiders' anatomy in very fine detail, pieces of amber show spiders mating, killing prey, producing silk and possibly caring for their young. In a few cases, amber has preserved spiders' egg sacs and webs, occasionally with prey attached; the oldest fossil web found so far is 100 million years old. Earlier spider fossils come from a few lagerstätten, places where conditions were exceptionally suited to preserving fairly soft tissues.
The oldest known exclusively terrestrial arachnid is the trigonotarbid Palaeotarbus jerami, from about 420 million years ago in the Silurian period, and had a triangular cephalothorax and segmented abdomen, as well as eight legs and a pair of pedipalps. Attercopus fimbriunguis, from 386 million years ago in the Devonian period, bears the earliest known silk-producing spigots, and was therefore hailed as a spider at the time of its discovery. However, these spigots may have been mounted on the underside of the abdomen rather than on spinnerets, which are modified appendages and whose mobility is important in the building of webs. Hence Attercopus and the similar Permian arachnid Permarachne may not have been true spiders, and probably used silk for lining nests or producing egg-cases rather than for building webs. The largest known fossil spider as of 2011 is the araneid Nephila jurassica, from about 165 million years ago, recorded from Daohuogo, Inner Mongolia in China. Its body length is almost 25 mm.
Several Carboniferous spiders were members of the Mesothelae, a primitive group now represented only by the Liphistiidae. The mesothelid Paleothele montceauensis, from the Late Carboniferous over 299 million years ago, had five spinnerets. Although the Permian period 299 to 251 million years ago saw rapid diversification of flying insects, there are very few fossil spiders from this period.
The main groups of modern spiders, Mygalomorphae and Araneomorphae, first appear in the Triassic well before 200 million years ago. Some Triassic mygalomorphs appear to be members of the family Hexathelidae, whose modern members include the notorious Sydney funnel-web spider, and their spinnerets appear adapted for building funnel-shaped webs to catch jumping insects. Araneomorphae account for the great majority of modern spiders, including those that weave the familiar orb-shaped webs. The Jurassic and Cretaceous periods provide a large number of fossil spiders, including representatives of many modern families.

Like many British manufacturers, AC Cars had been using the Bristol straight-6 engine in its small-volume production, including its AC Ace two-seater roadster. This had a hand-built body with a steel tube frame, and aluminium body panels that were made using English wheeling machines. The engine was a pre-World War II design by BMW which by the 1960s was considered dated. Bristol decided in 1961 to cease production of its engine and instead to use Chrysler 313 cu in (5.1 L) V8 engines. AC started using the 2.6 litre Ford Zephyr engine in its cars. In September 1961, American automotive designer Carroll Shelby wrote to AC asking if they would build him a car modified to accept a V8 engine. AC agreed, provided a suitable engine could be found. Shelby went to Chevrolet to see if they would provide him with engines, but not wanting to add competition to the Corvette they said no. However, Ford wanted a car that could compete with the Corvette and they happened to have a brand new engine which could be used in this endeavor: Ford's 260 in³ HiPo (4.2 L) engine – a new lightweight, thin-wall cast small-block V8 tuned for high performance. Ford provided Shelby with two engines. In January 1962 mechanics at AC Cars in Thames Ditton, Surrey fitted the prototype chassis CSX2000 with a 260 ci Ford V8 borrowed from Ford in the UK; the 221 ci was never sent. However, early engineering drawings were titled "AC Ace 3.6". After testing and modification, the engine and transmission were removed and the chassis was air-freighted to Shelby in Los Angeles on 2 February 1962. His team fitted it with an engine and transmission in less than eight hours at Dean Moon's shop in Santa Fe Springs, California, and began road-testing.
Production proved to be easy, since AC had already made most of the modifications needed for the small-block V8 when they installed the 2.6 litre inline 6 Ford Zephyr engine, including the extensive rework of the AC Ace's front end bodywork. The most important modification was the fitting of a stronger rear differential to handle the increased engine power. A Salisbury 4HU unit with inboard disc brakes to reduce unsprung weight was chosen instead of the old E.N.V. unit. It was the same unit used on the Jaguar E-Type. On the production version, the inboard brakes were moved outboard to reduce cost. The only modification of the front end of the first Cobra from that of the AC Ace 2.6 was the steering box, which had to be moved outward to clear the wider V8 engine.
AC exported completed, painted and trimmed cars (less engine and gearbox) to Shelby who then finished the cars in his workshop in Los Angeles by installing the engine and gearbox and correcting any bodywork flaws caused by the car's passage by sea. A small number of cars were also completed on the East Coast of the USA by Ed Hugus in Pennsylvania, including the first production car; CSX2001.
The first 75 Cobra Mk1 models (including the prototype) were fitted with the 260 cu in (4.3 L). The remaining 51 Mk1 models were fitted with a larger version of the Windsor Ford engine, the 289 cu in (4.7 L) V8. In late 1962 Alan Turner, AC's chief engineer completed a major design change of the car's front end to accommodate rack and pinion steering while still using transverse leaf spring suspension. The new car entered production in early 1963 and was designated Mark II. The steering rack was borrowed from the MGB while the new steering column came from the VW Beetle. About 528 Mark II Cobras were produced in the summer of 1965 (the last US-bound Mark II was produced in November 1964).
Since late 1962 when the new GM Stingray was shown up briefly by the Mk1 Cobra (until hub failure intervened) the development of the Grand Sport Corvette program had continued at a pace and was thought to be going for a build series of 125 cars. This would allow GM to compete directly in the FIA GT class of racing. Just to compound this Enzo Ferrari was trying to pull another "fast one" on the FIA with the request for the homologation of the 250LM. The FIA had not forgotten the serious lack of production of the 250GTO, which it had granted homologation in advance of Enzo's assured 100 minimum per year. Just thirty-six were produced over three years with two very different chassis, neither of which were too similar to the 250 GT which was supposed to form the basis of the vehicle. In an effort to prepare for the task ahead alternative engines were considered. The 289 cu in (4.7 L) leaf-spring Cobra dominated the US domestic race series (USRRC), with only one race lost in three years. The results in the FIA GT class were different. This was mainly due to the number of circuits that had much higher sustained speeds. Aerodynamics were more important and put the roadster at a disadvantage. As a result, coupe versions were built.
A stroker 289 (325),and the larger 390/427 up to the "cammer" 427 was considered. Shelby was told at the eleventh hour to use the iron 427 cu in (7.0 L). There was little time to fully develop a competition vehicle. The coil spring Cobra production was slow and an insufficient number made to meet FIA's GT homologation. Therefore the S/C (Semi – Competition) was produced by making available to the general production the full race options for the street. By now Enzo was having races recategorised in Italy to prevent the almost inevitable defeat on home soil as the 250LM was not homologated as a GT and would have to run as a prototype. GM had pulled the plug on the Grand Sport and so the five chassis that were built had to run as prototypes and so were placed in a difficult position to say the least.
Shelby had earlier in 1964 fit a larger Ford FE engine of 390 cubic inches (6.4 L) in to CSX2196. Unfortunately the car was not able to receive the development it needed as resources were aimed at taking the crown from Ferrari in the GT class. Ken Miles drove and raced the FE-powered Mark II at Sebring and pronounced the car virtually undriveable, naming it "The Turd". It failed to finish with the engine expiring due to damper failure. A new chassis was required developed and designated Mark III. CSX2196 was revised for the show down at Nassau which allowed a more relaxed class division of racing. This allowed the GT cobras to run with prototype Ford GT, GM Grand Sport Corvettes and Lola Mk.6. The first meeting at which the GS Corvettes showed up was in 1963. It was for this event in 1964 that the Fliptop cobra was used. An aluminium 390 cubic inches (6.4 L) engine was used. However, the car failed to finish.
The new car was designed in cooperation with Ford in Detroit. A new chassis was built using 4 in (102 mm) main chassis tubes (up from 3 in (76 mm)) and coil spring suspension all around. The new car also had wide fenders and a larger radiator opening. It was powered by the "side oiler" Ford 427 engine (7.0 L) rated at 425 bhp (317 kW), which provided a top speed of 164 mph (262 km/h) in the standard model and 485 bhp (362 kW) with a top speed of 185 mph (298 km/h) in the competition model. Cobra Mark III production began on 1 January 1965; two prototypes had been sent to the United States in October 1964. Cars were sent to the US as unpainted rolling chassis, and they were finished in Shelby's workshop. Although an impressive automobile, the car was a financial failure and did not sell well. In fact to save cost, most AC Cobra 427s were actually fitted with Ford's 428 cubic inches (7.01 L) engine, a long stroke, smaller bore, lower cost engine, intended for road use rather than racing. It seems that a total of 300 Mark III cars were sent to Shelby in the USA during the years 1965 and 1966, including the competition version. 27 small block narrow fender versions, which were referred to as the AC 289, were sold in Europe. Unfortunately, The MK III missed homologation for the 1965 racing season and was not raced by the Shelby team. However, it was raced successfully by many privateers and went on to win races all the way into the 1970s. The remaining 31 unsold examples were detuned and fitted with wind screens for street use. Called S/C for semi-competition, an original example can currently sell for 1.5 million USD, making it one of the most valuable Cobra variants.
Shelby wanted the AC Cobras to be "Corvette-Beaters" and at nearly 500 lb (227 kg) less than the Chevrolet Corvette, the lightweight roadster accomplished that goal at Riverside International Raceway on 2 February 1963. Driver Dave MacDonald piloted CSX2026 past a field of Corvettes, Jaguars, Porsches, and Maseratis and recorded the Cobra's historic first-ever victory. Later, Shelby offered a drag package, known as the Dragonsnake, which won several NHRA National events with Bruce Larson or Ed Hedrick at the wheel of CSX2093. Only five Dragonsnake Cobras were produced by the factory, with three others (such as CSX2093) prepared by customers using the drag package.
An AC Cobra Coupe was calculated to have done 186 mph (299 km/h) on the M1 motorway in 1964, driven by Jack Sears and Peter Bolton during shakedown tests prior to that year's Le Mans 24h race. A common misconception is that this incident persuaded the British Government to introduce the 70 mph (110 km/h) maximum speed limit on UK motorways, which up until that year had no speed restrictions, although government officials have cited the increasing accident death rate in the early 1960s as the principal motivation, the exploits of the AC Cars team merely highlighting the issue.
The AC Cobra was a financial failure that led Ford and Carroll Shelby to discontinue importing cars from England in 1967. AC Cars kept producing the coil-spring AC Roadster with narrow fenders, a small block Ford 289 and called the car the AC 289. It was built and sold in Europe until late 1969. AC also produced the AC 428 until 1973. The AC Frua was built on a stretched Cobra 427 MK III coil spring chassis using a very angular steel body designed and built by Pietro Frua. With the demise of the 428 and succeeding 3000ME, AC shut their doors in 1984 and sold the AC name to a Scottish company. The company's tooling, and eventually the right to use the name, were licensed by Autokraft, a Cobra parts reseller and replica car manufacturer owned by Brian A. Angliss.
This photo is shot with a modified lens. I removed one of the glasses inside and turned the rear glass 180 degr. The picture has a bit of sharpness in the center and a very strange affect on the sides and the corners.
