I just got my Granddaddy's S&W 38 Special CTG. I know it was bought before 1972, because that was the year that my Granddaddy died. He owned a Motel and two gas stations and had this gun for his protection against someone robbing him. It is nickel plated with mother of pearl handles, it has a 3" barrel. It has 38 S&W Special CTG on rightside of barrel, on top of barrel I can only read SA Patented and under that I see 09 DEC 29 14. It looks like the the site is on top of part of the information that is there. And on the leftside of the barrel it has Smith & Wesson. It is a double action 6 shot. The serial number on bottom of hand grip is 3175**. So the only thing that I know about this gun is that it is at least 35 years old. Hopefully someone can tell me about when it was made and anything else I might need to know about this gun.
