I'd like to know more about a gun I have that belonged to my great grandfather. It's a Smith & Wesson .38, pearl grips, nickel plated revolver. I don't know the model number. The serial number, located on the bottom of the grips, is 239xx. It has the following along the top of the barrel between the sights: "Pat'd Aug 4 86 Dec 22 86 Oct 8 07 Feb 8 06 Sept 24 00". The nickel plating is badly worn, but the pearl handles are beautiful. If anyone knows anything at all about this gun, I'd really appreciate hearing from you.
