For the last year and a half I've been trying to find a replacement ratchet for a Colt Police Positive Special in 32-20 w.c.f. At some point during this revolvers life a hatchet man of a gun smith misformed the hand causing the ratchet to wear abnormally. While I have been able to find a new hand the ratchet has eluded me for some time. I've searched for the part at (Numrich Gun Parts, Colt, Jack First, Larry Gun Parts, Pennsylvania Gun parts and a few others). I've also taken to scouring tables at gun shows for the part. So far no luck. I could really use some help in finding this part or a gun in the same caliber that can be used for parts. Thanks for the help in advance.
