A high quality lock assembled with precision from well designed components. Features a stirrup between the mainspring and tumbler, a roller bearing on the frizzen, bearing surfaces on the tumbler and sear and a "waterproof" pan which give the best ignition speed possible. Right hand only. Measures 5-5/8" long x 1" wide. No. 43300
