Francesco describes the Fine Molds kit as not a 'shake and bake' experience but believes an average modeller should be able to build it without problems. He riveted the completed model using FAOW drawings for reference. Some details were scratch built such as copper wire spark plug cables to the engine, lead wire and stretched sprue for the landing gear hydraulic cables, but he also added aftermarket generic Eduard JAAF seat belts and a Yahu instrument panel.
He felt his real challenge was trying to nail the correct shade of paint for the Tachikawa factory finish to emphasise its brown tone. Eventually he settled on a mix of Gunze paints - H70 RLM 02 + H81 Khaki + H84 Mahogany + H421 RLM 81. For the under surface colour he mixed Tamiya paints XF52 Flat Earth + XF55 Deck Tan based on the description of Mr Noburo Shimoune in a 1968 Koku Joho magazine supplement, reported here in February 2009 as follows: 'I want to say that the underside colour was gray, but it was not Nezumi-iro (rat or mouse colour). Rather it was a colour similar to the top colour but lightened with white.' In 2004 an extant sample of this paint was compared as close to FS 36405 Gray.
All the markings were painted on using masks except the unit insignia decal which unfortunately broke up and had to be repaired at best endeavour. The insignia represented the numbers '3' and '9' said to be in the form of a swallow.
