A friend of mine lost the cylinder pen and lock screw out of one of these pistols and can not find one. The only place we knowed to check was Numerich gun parts and they did not have anything but a barrel for one left. I have had contacts for other places but have lost them and do not remember the names of them. This is a cheap 22 cal. pistol that he uses to check his traps with. Anybody know where to get parts for this gun?
