The Colt Third Model Dragoons were the last of Colt's massive "horse pistols" descended from the Colt Walker and were manufactured from 1851 to 1861 and were replaced with the more manageable Colt Model 1860 Army revolvers. Unlike the Walker and Dragoons, the Army was small enough to be in a belt holster making it useful for a wider variety of troops than the larger revolvers that were designed to be carried in pommel holsters. This Third Model Dragoon was manufactured in 1855 and has a German silver blade front sight, "-ADDRESS SAML COLT NEW-YORK CITY-" on the top of the barrel, the Texas Rangers and Indian battle roll-scene with "MODEL U.S.M.R." (U.S. Mounted Riflemen). The frame has "COLTS/PATENT" on the left. The various components have all matching serial numbers. The cylinder also has "3" perpendicular to the serial number, and the trigger guard has an "A" and a "G" on the left.

Very good with traces of original finish, aged patina on the brass, mottled gray and brown patina on most of the iron, lighter patina on the cylinder which has a fairly distinct roll-scene, and generally mild overall wear. The grip is also very good and has moderate handling and storage wear, over half of the original varnish, edge wear, and minor chips at the toe. Mechanically fine.
