Not sure I replied previously ( grew up close by in West Seneca where my older brother was a long time officer and for quite a while the primary firearms instructor) back in the revolver era, it was not uncommon for agencies to have 22's for training purposes to help officers that might be having issues qualifying with the duty caliber, or departments that had "cadet" programs for youth interested in LE careers. Also back in the 50's/60's/70's and even into the 80's a lot of agencies had bullseye competition pistol teams and bullseye matches consist of shooting both 22's and centerfires so lots of possible reasons for a 22 in inventoryHere's one I posted before. Bought it at Cabelas. Salesman said an elderly retired Lancaster NY cop brought it in to sell. I can't figure out why a police dept would have a .22. Evidence? Range gun? Animal control? I don't know. I put the Buffalo Horn grips and Tyler T on it. It came with mismatched diamond magnas. Great shape otherwise. Shoots as you would expect.
I'm not a tool mark expert... so I could be wrong. But, to me the "11" appears to have been applied by a hammer and punch, after the sideplate was wire brushed to remove pitting. However, without seeing the other side, and the frame behind the cylinder yoke, plus both sides of the grip fame, I'd say this looks like a 4" S&W 64-5 police trade-in. Additionally, what's the three letter serial number prefix? That might match up to other known New York trade-ins:View attachment 771580
64-5 no markings other than the 11 stamp. Was in really rough shape when I got it so I put a finish on it that I like.
A Gander Mountain sporting goods department manager in New York thought my S&W 10-6 marked "JP 550" was from Jacksonville, Florida PD. It took just twenty minutes to locate the connection to Jordanian National Police.This is a great thread! I found out that the model 10 I have and assumed was imported from a French PD, because that is what the online dealer said, is actually from Jordan.
