Both shipped in 1949. One to NYPD the other LAPD.
The history of that LAPD snubbie would be interesting. I don't know much about what they did in LA in 1949. But up until the mid 60s, everyone carried a 6" K-38 or M10. Uniforms and dicks all carried the same bbl.
If they indeed didn't issue snubs in 49, then this one might have some kind of very special history. Like the chief of police carried it etc.
