Trying to figure out how old my pistol is did find model number behind yoke it is a 32 LONG model 45511 and i think the serial number is 413675

Welcome to the Forum Terry,
The numbers behind the yoke on the frame are typically S&W assembly numbers. The actual serial# is on the bottom of the grip frame between the 2 halves of the stocks. I 'll give you a link to follow to provide more detail so members can help you figure out what you have.

Welcome aboard from Wyoming.

I'd bet 413675 is your serial number. I'm by no means an authority, but I'd put it in the mid-1920s. The authorities will be along to, perhaps, give you a better approximation.

Cheers,

Bob
