Military Rifles of Japan by Fred Hunnicut and F. Patt Anthony covers quite a lot of ground on the subject and has photos of the different types, production series and variants. And there are several other less expensive books out there. Might want to see if yours has matching assembly numbers. Numbers are on bayonet lug, bolt, extractor, firing pin, dust cover. etc. They spent more time stamping numbers on their rifles than polishing. Numbers may or may not match last three of s/n depending on manufacturer.
Thanks for the info. All numbers match except for the bolt. Too bad. All matching would have been nice, but sounds like very unrealistic.
