Ruger Brass Frame Super Blackhawk 3 Screw Model. This is an early model Super Blackhawk with a low 5 digit serial number (15XXX). It has not had the factory safety conversion and has factory Ruger Brass Frame (will not letter as being shipped with a Brass Frame). Brass frame shows some scratches on the backstrap (see pic). The gun is in very nice shape as I would rate it 98%. Very clean Old Ruger. Please email with any questions or for additional pictures. Sorry, no sales to CA.
