Some background:
The Nakajima J9N Kitsuka (中島 橘花, "Orange Blossom", pronounced Kikka in Kanji used traditionally by the Japanese) was Japan's first jet aircraft. In internal IJN documents it was also called Kōkoku Nigō Heiki (皇国二号兵器, "Imperial Weapon No.2"). After the Japanese military attaché in Germany witnessed trials of the Messerschmitt Me 262 in 1942, the Imperial Japanese Navy issued a request to Nakajima to develop a similar aircraft to be used as a fast attack bomber. Among the specifications for the design were the requirements that it should be able to be built largely by unskilled labor, and that the wings should be foldable. This latter feature was not intended for potential use on aircraft carriers, but rather to enable the aircraft to be hidden in caves and tunnels around Japan as the navy began to prepare for the defense of the home islands.
Nakajima designers Kazuo Ohno and Kenichi Matsumura laid out an aircraft that bore a strong but superficial resemblance to the Me 262. Compared to the Me 262, the J9N airframe was noticeably smaller and more conventional in design, with straight wings (lacking the slight sweepback of the Me 262) and tail surfaces. The triangular fuselage cross section characteristic of the German design was less pronounced, due to smaller fuel tanks. The main landing gear of the Kikka was taken from the A6M Zero and the nose wheel from the tail of a Yokosuka P1Y bomber.
The Kikka was designed in preliminary form to use the Tsu-11, a rudimentary motorjet style jet engine that was essentially a ducted fan with an afterburner. Subsequent designs were planned around the Ne-10 (TR-10) centrifugal-flow turbojet, and the Ne-12, which added a four-stage axial compressor to the front of the Ne-10. Tests of this powerplant soon revealed that it would not produce anywhere near the power required to propel the aircraft, and the project was temporarily stalled. It was then decided to produce a new axial flow turbojet based on the German BMW 003.
Development of the engine was troubled, based on little more than photographs and a single cut-away drawing of the BMW 003. A suitable unit, the Ishikawa-jima Ne-20, was finally built in January 1945. By that time, the Kikka project was making progress and the first prototype made its maiden flight. Due to the worsening war situation, the Navy considered employing the Kikka as a kamikaze weapon, but this was quickly rejected due to the high cost and complexity associated with manufacturing contemporary turbojet engines. Other more economical projects designed specifically for kamikaze attacks, such as the simpler Nakajima Tōka (designed to absorb Japanese stock of obsolete engines), the pulsejet-powered Kawanishi Baika, and the infamous Yokosuka Ohka, were either underway or already in mass production.
The following month the prototype was dismantled and delivered to Kisarazu Naval Airfield where it was re-assembled and prepared for flight testing. The aircraft performed well during a 20-minute test flight, with the only concern being the length of the takeoff run – the Ne 20 only had a thrust of 4.66 kN (1,047 lbf), and the engine pair had barely sufficient power to get the aircraft off the ground. This lack of thrust also resulted in a maximum speed of just 623 km/h (387 mph, 336 kn) at sea level and 696 km/h (432 mph; 376 kn) at 10,000 m (32,808 ft).
For the second test flight, four days later, rocket assisted take off (RATO) units were fitted to the aircraft, which worked and gave the aircraft acceptable field performance. The tests went on, together with a second prototype, but despite this early test stage, the J9N was immediately rushed into production.
By May 1945 approximately forty airframes had been completed and handed over to IJN home defense frontline units for operational use and conversion training. These were structurally identical with the prototypes, but they were powered by more potent and reliable Ne-130 (with 8.826 kN/900 kgf) or Ne-230 (8.679 kN/885 kg) engines, which finally gave the aircraft a competitive performance and also made the RATO boosters obsolete - unless an 800 kg bomb was carried in overload configuration. Most of them were J9N1 day fighter single seaters, armed with two 30 mm Type 5 cannons with 50 rounds per gun in the nose, but a few were unarmed two-seaters (J9N2) with dual controls and a second seat instead of the fuselage fuel tank, what markedly limited the aircraft’s range but was accepted for a trainer.
Some operational Kitsukas also had, due to the lack of equipment, the 30 mm guns replaced with lighter 20 mm Ho-5 cannon. A small number, both single- and two-seaters, were also equipped with an experimental centimeter waveband FD-2 radar in the nose with an “antler” antenna array, similar to German radar sets of the time. In order to fit the electronics, the machines typically had one of the nose-mounted guns replaced by a fixed, obliquely firing Ho-5 gun ("Schräge Musik"-style) behind the cockpit. These machine received the suffix “-S” and flew a few quite effective missions against American B-29 bombers, but their impact was minimal due to the aircrafts’ small numbers and poor reliability of the still experimental radar system.
Proposed follow-on versions had included a reconnaissance aircraft and a fast attack aircraft that was supposed to carry a single bomb under the fuselage against ships. There was also a modified version of the design to be launched from a 200 m long catapult, the "Nakajima Kikka-kai Prototype Turbojet Special Attacker". All these proposed versions were expected to be powered by more advanced developments of the Ne-20, the Ne-330 with 13 kN (1.330 kg) thrust, but none of them reached the hardware stage.
The J9Ns’ war contribution was negligible, and after the war, several airframes (including partial airframes) were captured by Allied forces. Three airframes (including a two-seat night fighter with FD-2 radar) were brought to the U.S. for study, two damaged day fighters were handed over to the RAF and transferred to RAF Seletar, where the airframes were, together with spares, combined into a single flyworthy J9N1 designated “FE (Foreign Equipment) 269” and tested by the Allied Technical Air Intelligence Unit. These tests did not last long, though, because the engines were in poor condition and only lasted for four test flights until one failed fatally and caused a fire: at least one compressor blade had separated and ruptured fuel and oil lines. The pilot was able to leave the burning and disintegrating aircraft but was hit by the tail and was badly injured. However, he survived, but FE 269 crashed into the Street of Sohor.
Today, two J9N examples survive in the National Air and Space Museum: The first is a Kikka that was taken to the Patuxent River Naval Air Base, Maryland for analysis. This aircraft is very incomplete and is believed to have been patched together from a variety of semi-completed airframes. It is currently still in storage at the Paul E. Garber Preservation, Restoration and Storage Facility in Silver Hill, MD.
The second Kikka is on display at the NASM Udvar-Hazy Center in the Mary Baker Engen Restoration Hangar.

The kit and its assembly:
This is submission #4 for the “Captured!” group build at whatifmodellers.com in late 2020. Loot from WWII certainly makes a good theme, and I remembered a real world J2M3 that I had built some time ago – in RAF markings and tested by the ATAIU-SEA in Singapore in late the 1945. For a more whiffy touch I delved through The Stash™ for options and found an AZ Models Nakajima “Kikka” single seater – as Japan’s first jet fighter, a suitable contender, even more so because no aircraft of this type made it in time to frontline units.
The AZ Models kit is a simple affair, but that's also its problem. In the box things looked quite good, detail level is on par with a classic Matchbox kit. But unlike a Matchbox kit, the AZ Models offering does not go together... I had to fight everywhere with poor fit, lack of locator pins, ejection marks - anything a short run model kit can throw at you! Things turned out really bad: One upper wing half was bent so much that I tried to counter the flaw with force - and the part broke! Furthermore, PSR was necessary almost everywhere – but especially around the wing/engine pod intersection and the area where the wings are inserted into the fuselage. Huh! What worked surprisingly well is the IP canopy, though.
Personal additions are lowered flaps (easy to realize) and some additional struts for the landing gear.
Painting and markings:
The captured aircraft theme was settled from the start, but I wanted to offer more than just a “rebadging” with RAF roundels on an IJN green/grey airframe. In order to add some visual spice, my idea became to present an irregular "one-aircraft-made-from-two-wrecks" finish, with parts in differing tones and even some primed or bare metal areas.
I gave the model an overall coat of aluminum (with Red Stars added, this would have made another interesting whif!) and started adding cloudy shades of IJN Green (ModelMaster and Tamiya) and sections with RAF Dark Green to the upper surfaces, and light grey underneath, with the aluminum underneath shining through here and there. One engine was furthermore painted in a shaggy Japanese primer red brown. I furthermore added overpainted IJN markings with U.S. olive drab for some more contrast, even though would later be at least partly hidden under decals.
The cockpit was painted in a greenish yellow primer (trying to simulate a typical “bamboo” shade that was used in some late-war IJN cockpits), while the landing gear and the flaps’ interior was painted in dull aluminum (Humbrol 56).
A black ink washing was applied for more weathering and contrast. the yellow leading edge markings were created with decal material. RAF roundels came from the scrap box, the “FE 269” code was created with single white 3mm letters. The “ATAIU-SEA” titles were painted with a thin brush and white acrylic paint, and sanded down a bit once dry, for a weathered look.
Finally, the kit received a mixed coat of semi-gloss and matt acrylic varnish.
I had the Kikka earmarked for a different build, but I think this ATAIU livery adds an interesting twist to the model, it looks pretty plausible. Besides, the Kitsuka is a pretty, elegant aircraft, and it's relatively small (even petit) when compared with a contemporary Me 262 or a Meteor!
What???? What???? What???
Here is the back story: I bought 19 boxes of doll clothes gambling that their would be some awesome vintage clothes and there ARE!!! BUT, yes there is a but, :( I observed the boxes were moldy. The seller said yes but the clothes were all in plastic bags. With the exception of a few clothes here and there the doll clothes were in plastic bags with one other HUGE exception. NONE of the vintage Barbie clothes in two different boxes were in plastic bags. One box was no problem as the mold had not penetrated the box BUT, oh yes another BUT, the other box had more mold than any of the other 19 boxes. It had penetrated the bottom, entered the inside of the box and contaminated the clothes!!! Oh what a heartbreak. I blew as much mold as I could off with air from an air compressor and stuck them in a plastic bag. I googled clothes and mildew where I read from several sites that borax kills mold and gets rid of stains in clothes. Also that it was good for dumping down your sinks. NO WAY!!! Crystals in my pipes??? I get ahead of the story. I thought it would be a good experiment to try the borax on some Calico Critters that had never been removed from their boxes BUT mold had also penetrated their boxes. Maybe borax would work on cloth but CRYSTALS??? Is it a chemical reaction to plastic? Some plumbing pipes are plastic!!! Information said borax worked well in dishwashers but there is plastic in dishwashers. Maybe I should have added detergent to the borax solution. It all makes my head hurt. In conclusion the borax did NOT work!!! I had to soak the critters in really HOT water to get the crystals to dissolve and the mold was still there.
The Broomwade Air Compressor looking factory fresh, after its recent restoration. A fantastic job has been done with this.
Air tools are used to maintain the railway and this wagon has been built on a bogie to provide an air supply on site.

I was up in San Francisco visiting friends. I met up with rustyjaw , TunnelBug, Dead Slow and Larry (sorry don't know your screen name) to do some exploring.
Rustyjaw suggested the location and it was great fun exploring the halls, various staircases and machinery left laying around.
Thanks guys, was greet meeting/seeing you all. We have to do that again sometime.

This model was first introduced in late 1922. Very cool air compressor. Has brass valves with Brunner Mfg Co. embossed on them and the black handles have little "B" on them. The motor is the original "Westinghouse Electric made for Brunner" with the last patent date of December 30th, 1919! Doing some online research I have found that Brunner was in business from about 1905 into the early 80's.This unit had a cost in 1923 of 370 dollars with a shipping weight of 630 pounds! Still trying to learn about this heavy beast. It ran when I got it but disassembled some outer components to clean them up and have some confusion for reassembly. Anyone with info please email me. Thanks
