A relative passed away recently. We are going through her estate and found a Ruger single six revolver in her personal property. We are trying to figure out its worth (if anything) and decide if we should keep it or put it up for auction when her estate is sold. On the left side of the gun it says "Ruger .22 cal. single six" and on the right side is the number "5020". The barrel is 5 1/2 inches long. It is a 3 screw model and does not have a flat loading gate. It was found in a leather holster with brass snaps that say "Brauer Bro's MFG. CO. St. Louis". The holster is a little moldy, but the gun is in good shape, very clean, with some scratches. Can anyone tell me anything about this gun, its worth, or anything else. Thanks for your help.
