Colt 1851 Navy Revolver

The Colt Revolving Belt Pistol, commonly called the Navy Pistol, is a .36 caliber, six round cap and ball revolver designed by Samuel Colt between 1847 and 1850 and introduced in 1851. It was originally called the Ranger Size model and then the Revolving Belt before the Navy name became standard, and it remained in production until 1873, when the Colt Single Action Army replaced it. Roughly 215,000 were made domestically along with about 42,000 more from the Colt London Armory.
