Manufactured in 1850, this is a desirable U.S. inspected Colt Second Model Dragoon revolver. Only an estimated 2,700 Second Model Dragoons revolvers were manufactured around 1850 and 1851 compared to 7,000 of the First Model Dragoons and 10,500 Third Model Dragoons. A large percentage of these revolvers were manufactured for the U.S. Army. The revolver has the distinctive combination of squareback trigger guard and rectangular cylinder stops, which are second model features. The part round barrel is fitted with a German silver blade front sight and is stamped with the one-line "-ADDRESS SAML COLT NEW-YORK CITY-" address, the left side of the frame is stamped "COLT'S/PATENT/U.S." and the cylinder is roll-engraved with the Ranger and Indian fight scene and "MODEL U.S.M.R./8866/COLT'S PATENT". Matching serial numbers visible on the loading lever, barrel, frame, trigger guard, butt, cylinder, cylinder pin, and correctly handwritten in black ink inside the back channel of the grip, with non-matching number "0696" on the period replacement wedge. Single letter inspector marks are visible on the loading lever, frame, cylinder, hammer and trigger guard.

Very good, exhibiting a mix of smooth gray and brown patina with some noticeable areas of scattered light to moderate pitting, mostly clear markings in the metal, and bright golden appearance on the brass. Cylinder scene is fine, mostly intact. Grip is also very good as re-oiled with general wear, and scattered dents and scratches. Mechanically excellent.
