I think I read that the Type 1 was issued, maybe on a limited basis, but they started having problems with the welds cracking and such, so they were withdrawn and the forged rec type was issued. 80,000 was mentioned, but nobody knows for sure how many were made, top secret info behind the iron curtain. "The Gun" by C.J. Chivers gives a good as it gets account. If you can get past the slightly anti gun rhetoric.
