Need D.O.B. for 3 Colt revolvers please?

[Bob1911]

The first is a Colt Officers model .38 Spl Ser# 328120

The second is a Colt Police Positive .38 Spl Ser# 401733

The Third is a Colt Polise Positive .38 S&W Ser# 167164

The first and second were my father's and the third is mine bought recently because the first two went to my sister.

Any help is greatly appreciated.

Thank you,
Bob Russell
