It's not the Shinden, Donuel, it's the Shiden. The Shiden is a conventional fighter which was developed from the Kawanishi floatplane "Rex". It's a midwing monoplane, conventional arrangement, was used in '44-'45 by the Japanese Navy. Revell made a 1/32 scale kit of it in the early 70's, and it's become very rare. There are, however, plenty of Shidens in 1/48 scale, including Tamiya's and the new Hasegawa rendition, both excellent kits.
