   Their are some awsome computer images as well, if my scaner was up I would scan them for you.
   I found a Great source for Japanese Books Kinokuniya book stores, I beleave it is a chain store their Oregon phone Number is 503-641-6240, they will ship it for you as well, and if they dont have it they can order it from Japan. For years I have looked for decent images and drawings of Japanese planes and Ship's tanks and I have found the mother load:)
