I don't know how this rifle wound up in Canada. Turned up in Eastern ON. There are some in US collections. Maybe this one came north. Very few Canadians were in Japan in '45. They are certainly very rare in this country, uncommon in the US. Probably the only ones that survived were taken as souvenirs or study examples. Many Japanese arms were brought to the US by returning servicemen. A lot of standard rifles remained in service in China, Korea, SE Asia. As far as value goes, I don't really know. I've not seen another one sell or advertised. They are worth a lot less than the German equivalents. A VG1 or VK98 will bring thousands. This one is in pretty good shape. Its been handled, and has some nicks and dings, but overall it is in nice conditon. It is basically a copy of a very late "last ditch" Type 99 short rifle, with the different manufacturing methods. I'll take some more photos and post them.
Speaking of Japanese small arms, back in the '60s, I saw a Nambu light machinegun for sale in a shop in London, ON. It had pockmarks from fragments on its receiver, and the barrel cooling fins were grooved on top by an incoming bullet. No idea if it had been captured during WW2 or in Korea.
