Rare 3-screw old model Super Blackhawk with 2-digit serial number (39) and long grip frame, in the factory mahogany case. Only about 300 guns were made with the long frame. This one has not been altered for the transfer bar safety. The gun shows plenty of wear, primarily in the cylinder which has lost all of its finish. The barrel and frame have about 70% of the finish. The grips are good with wear matching the condition of the gun. The case is very good with some light wear on the outside and a good looking interior with proper factory label. A rare and historical Ruger revolver.
