The Taylor’s & Co C. Mason 1851 Navy Revolver features a brass backstrap and triggerguard, octagonal barrel with brass post front sight, and a smaller-size Navy grip. All C. Mason models feature a case-hardened forged steel frame, blued finish parts, modern ejector rod, and hammer with notched rear sight. With patents for the conversion of percussion revolvers, Colt employees Charles Richards and William Mason cut off the cap-and-ball cylinders at the back and installed a conversion ring to accept cartridges. These conversion revolvers were favorites then and are enjoying popularity again as favorite reproductions.
