I'm new to this site. I see some of you have similar interests in a particular model of S&W pistol. I have a pristine Model 39, no dash, 9mm pistol with a serial number 80900. Does anyone know about what year it was manufactured? I've been told it was bought in the '50s but the instruction sheet in the box, yes I have the original box, notes that prices for replacement parts are effective January 1, 1960. I have no idea if the instruction sheet is the original one, either.
