I just picked up a "parts" gun with not much wrong with it or missing. Stock is cracked but certainly fixable for a shooter. Bore is very good. Looks like someone took the sear off of the sear bracket and lost the rivet/ sear spring stud. My question is will the sear assembly from a 99C work on it. Numerich list the C as part #142120C and the brush gun as # 142120A. Any one had to replace one? My options are to pull one out of a junk 22 250 C or try to make a new rivet to fix the original. Even if Numerich had one, they don't ship to Canada, so options are limited.
