Thanks for the help everyone.
Serial Number is 138184
My father died in 2000 and neither gun has been fired since then. That is why I used the old pic, they just sit in the safe. The cylinder stop hasn't worked for as long as I can remember (40-50 years). The 32 S&W is in awesome condition and perfect working order. The 38 has been refinished I think. I'm not sure but the S&W logo on the gun doesn't seem to be as deep and crisp as on the 32, that is my only reasoning for saying it has been refinished at some point. So early in its life it might have been used some or a lot? A gunsmith says the stop is worn down. I hope he knows what he is talking about. He cleaned and lubricated it and it still didn't work.
