My NYPD Midel 640 looks just like yours and it shipped in March of 1993. It has that same frosted finish that the Job mandated. Surely isn't a bigger East Coast PD out there. They were authorized for off duty use until 1996. Guys who had them could keep them but no new revolvers for new hires after 1996. In 2018, the Job mandated the remaining 200 or so who still carried a duty revolver would have to switch, but they couldn't mandate you to give up your off duty so they kept ammo on hand. They should have let them keep the 4" service revolver. You would have had to have 26 years on the Job by then. They all would have been gone in a few more years. Those who still had them weren't on the street anyway. For whatever reason, the cops who kept their duty revolvers didn't take the free 9MM and three days off patrol to transition.
For giggles I went back to the police range last year with a couple of NYPD 5946's to have the range guys take a look under the hood. I also brought my 640. The range guy said "I don't know how to service that relic".
I sold my off duty 640 like a dope many years ago. Guys were selling them for really cheap, like $150, to buy a new off duty 9MM. But I found another one just like it from the NYPD and it resides in my safe. I carried my 640 in my pocket on patrol on the Brooklyn mean streets in the 90's and rode many a subway car at night with it and never felt unarmed. Bernie Goetz used his 5 shot Model 60 to end the night of the three guys mugging him so they still have their uses.
