Tell me about my S&W Model 13-3 357 Magnum revolver, S ANF89XX. Fixed sight, excellent condition.

Welcome to the forum.
Sounds like you've identified it.

What else do you want to know?

The ANF prefix was used in 1986. I assume that is what you wanted to know.

What I curious about is what does the SN identify what it was issued for, and it's origin. I found it in my father's things after he passed. He served from 1938-1978 USAF in many capacities. It will fill in a little more about his story. Do you need the full serial number. Thank you!

Since it wasn't made until 1986, it clearly had nothing to do with your dad's military service.

Its "origin" was S&W's Springfield, MA, production plant.

"what it was issued for" - for one thing it wasn't "issued," at least not by the USAF. So far as I know the AF didn't ever have any Model 13 revolvers, of any dash number. As for its being a possible LEO gun, who knows? Plenty of them were simply sold to distributors and jobbed to retail stores. Given its date of production, that is most likely where this one came from. Your dad apparently purchased it sometime during or after 1986. Not much mystery in that, nor does it tell you anything about your father's story, except that at one time he acquired a S&W Model 13-3.
