The Chinese had a pile of Japaneseicon equipment in 1945. As best as I know the big plant in Manchuria(Norinco) only made the Type 38, I have heard the Type 99 was only made in Japan. So all of the 7.62x39mm carbines are Type 38 rifles cut-down into neat carbines. Barrel was bored out to .310 and chamber was sleeved. Press fit sleeve with no cross pins to fold it in tight. When I was stationed in Wash DC I saw a pile at the Richmond, VA show around 1988-89 time frame. I actually got one to go turkey hunting in my area. But too many reports of the chambers backing out, so I gave up. Got transferred to Calif and that was that. Still have the carbine, upstairs.
