K 22 masterpiece

[FLY BOY]

Hello, I have a couple of Smith and Wesson‘s that was left to me and they’re both K 22 masterpiece. I was wondering what the relative dates would be of manufacturing. First one is K652915 and the second one is K101639 both probably in 98% condition thanks. The one has the El stag grips also has originals that came with it.

K101639 with the early high speed "fishhook" hammer likely shipped in 1951.
K652915 likely shipped in 1966.

K652915 likely shipped in 1966.

Yes, and that one most likely is marked MOD 17-2.
