Looks Japanese to me. Maybe a Ki. 36/55 "Ida"?
Bingo Mike - a Tachikawa Ki-55 Ida Army trainer.
The book is Japanese Aircraft Equipment 1940-1945 by Robert C. Mikesh, published by Schiffer in 2004 but I just got a copy. Chapters are devoted to Aircraft Instruments, Radio Equipment, Aerial Cameras, Machine Gun and Machine Cannon, Gunsights and Bombsights and Interior Colors and Coatings. More later.
