Grannies got a gun
I found out my grandmother has an older Smith and Wesson double action revolver. The S/N, or least what I think the is the S/N on the bottom of the butt, is 120XXX. The hammer (exposed) and trigger have an almost blued finish while the rest looks like a nickel type finish. It has a trigger guard. The last patent date listed on the barrel is Jan 3, 1982. Any help on the age and model would be appreciated. I'd like to get a rough value in order to buy it for a fair price and keep it in the family.
