Mustang51 and David:
Way back in the "dark ages", ca mid-1970s, there was a publication that was done by him on the Ki-61. It was about 50 pages, 8 1/2 x 14 inches (what we call "legal size") and the hard covers were a silver color. It was all in Japanese, contained some of the "usual" photos, and some drawings. These were in 1/48 and the color profiles were fold-outs about 1/24. A slick publication but contained some errors.

BTW, isn't "Mustang51" redundant?
