This is probably and oddball question, but what the heck. I have never disassembled a revolver. I just watched a pretty good video about disassembling a 1920‘s Police Positive and it seemed fairly straight forward, but I think I might look for an old beater revolver just to practice on before I ever think about disassembling my other Colts. So, if you were looking for an old beater revolver that would be fairly indicative of other Colts, what model would you look for?
