It would have taken time to get that done and the city was in a rush to get them on the streets for riot duty. I was appointed in 6/1966 and within 3-4 days after being sworn in, we were given a class on procedures and sent to the range to 'qualify' and had to get Blue uniforms right off of the rack and told to put the gray Probationary uniforms away and then put out in the streets of Brooklyn or the Bronx for Riot Control..
You can send them a picture and they can find out more of the background on your gun along with the date manufactured.
They will charge you for this service ($50 at the time this was written) and it is probably only worthwhile for older collectible guns which have no serial numbers.
If you post a pic of the gun, I should be able to tell what it is. The story of how he came to own the pistol was that he purchased it from another patrolman who was retiring. Remington has a serial # look up person in customer service. serial numbers range from 241,704 - 1,000,000 ( mfg. Can you tell us what are the markings on the backstrap ? ) Chris The numbers on the back are NYPD armory numbers.
They look like Model 10's, and are very similar, but predate the Model 10 by over 50 years. The pistol was hard chromed back in '83/'84 before my Dad retired from the job.
Open the cylinder and look on the frame first, for a model designation. Then, at the very least you'll know the exact model number. I know it has some age to it and definitely has seen a great deal of action. ORG On it, there is a listing under HANDGUNS: REVOLVERS The first catogory is called IDENTITY OF S&W REVOLVERS The info you're looking for will probably be available there, by giving the required info .. Especially if you can place it at any major events in your fathers career or the previous cops career.
