I did work on K-32's and K-80's,but on several occasions original 32's and early K-32's came in.Different parts.Could not find them and had to make what I could. Even on the modern K's,some parts are restricted.Try Ottsville and hope.I did work on a lot of 2 barreled guns and some were very expensive.A common problem is parts.That is why I like Citori,680 series,P's,K's, and M-21's.
