The Colt 1851 Navy is used in the show by William.
The "Colt Revolving Belt Pistol of Naval Caliber" (i.e. .36 cal), later known as the Colt 1851 Navy or "Navy Revolver", is a cap and ball revolver that was designed by Samuel Colt between 1847 and 1850. Colt first called this "Revolver Ranger" model; but the designation Navy quickly took over. It remained in production until 1873, when revolvers using fixed metallic cartridges came into widespread use. Total production numbers were exceeded only by the Colt Pocket models in development at that time, and numbered some 250,000 domestic and 22,000 units produced in the Colt London Armory.
