Ruger Single-Six Win. .22 RF MAG SA Revolver - 3-Screw Version

First Single-Six I've seen marked on the frame as a "Win. .22 RF Mag"; comes with two cylinders, neither are marked but no drag marks at all; looks unfired; 6.5" BBL has some very minor bluing loss at the muzzle; smooth wood grips; older version w/3-Screws in frame; has older vinyl zippered case; made in USA; great collector gun for the Ruger collector!
