Doyusha has been around for quite a while, at least twenty years. They primarily made aircraft and ships way back when. They have also done knock-offs of other companies work, some of them not too bad. They are probably most famous for releasing a Zero, Frank and a Tony (I think) in 1/32 scale after the great Revell "lost molds" fiasco. They also released a 1/200 (or 1/144 747--can't remember they scale now, but it was a nice kit), and have released some Apollo launch vehicles and other spacecraft. I don't know anything about this kit, most of thier previous releases have been in the "indifferent range" of modeling-- not much close up detail and simplified construction. Rumor had it when I worked at a LHS several years ago that they had an arrangement with "Mini Hobby Model" which was notorious for making knock-offs of other folks work-- but that was just a rumor, and I think Doyusha is a completely legitimate company in itself.
