This revolver was manufactured in 1850 and is marked with "-ADDRESS SAML COLT NEW YORK CITY-" on the barrel, "COLT'S/PATENT" on the left side of the frame, and matching serial numbers on the various components including the loading lever (wedge not matching). It features: cone front sight, hammer notch rear sight, barrel wedge over the screw, non-beveled loading cutout, square back trigger guard, and a smooth walnut grip. These "First Model" variants are only found in the first year of production and only 800 to 1,250 are estimated to have been produced.

Good. The revolver displays a mix of gray and brown patina and has patches of pitting, marks and scratches, and light oxidation. The loading rod has a welded repair. There are traces of original silver plating on the trigger guard bow. The exposed brass has an even aged patina. The grip is very good with a few small dings and light scrapes. Mechanically fine. Most of the markings are clear aside from the cylinder scene. This is a very rare and desirable Colt Model 1851 Navy variation.
