Help dating three smiths?

[HighVelocity]

I have three older S&W revolvers that I'd love to know how old they really are if anyone can help.

1) Model 19-3 4" serial 9K2xxx

2) Model 36 serial ABUxxxx

3) Model 36 serial 529xxx

1) Model 19-3 4" serial 9K2xxx -- 1975

2) Model 36 serial ABUxxxx -- Somewhere between JAN and OCT 1983

3) Model 36 serial 529xxx --- If indeed there's no letter prefix, it's most likely older than you are. Somewhere between 1962 and '69.
