Recently acquired a pre war, c.1930 Police Positive .38 Special. It has a brand new park finish (not my taste) the price was right...under $60.00...so I bought it. It was disassembled when I saw it...the guy had no clue how to reassemble. I had it up and running in about 10 minutes. It's out of time in double action. Single action it indexes perfectly. D.A. it is unreliable. There is end shake and side play of the cylinder when closed. The ratchet or ejector star appears to have a recess of smaller diameter than the cylinder release bolt. I tried exchanging parts from a set I had purchased from Sarco, years ago, from a similar vintage PPS. No improvement. As expected, the rollmarks are all faint from being polished or beadblasted, but the bore and cylinder is excellent. Initially, I bought it for a bench dummy for molding holsters, to replace a much better grade/condition model I have been using. As I said...the price was absurdly low. But this revolver seems to be serviceable as a shooter if repaired, although not a collectable due to the refinish. I realize revolver parts generally, are not "drop in" like most autos. But I'm wondering if there is a technique to get the old girl up on her feet again. Any suggestions?
