Manufactured in 1851, this is a desirable U.S. marked Colt Second Model Dragoon revolver. Only an estimated 2,700 Second Model Dragoon revolvers were manufactured around 1850 and 1851 compared to 7,000 of the First Model Dragoons and 10,500 Third Model Dragoons, making the Second Model Dragoon the scarcest. 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." in three lines, the cylinder is roll-engraved with the Ranger and Indian fight scene, and the trigger guard/gripstraps are factory silver plated on this example. "G" inspection initial marking below the serial number on the trigger guard, with an "H" on top of the backstrap. Matching serial numbers visible on the 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 "10150" on the period replacement loading lever and "2462" on the period replacement wedge.

Good, showing some frontier character, exhibiting mostly smooth gray patina with some scattered light pitting, applied brown patina on the hammer, 20% original silver plating concentrated around the trigger guard and top edges of the backstrap with a bright appearance on the exposed brass, and a faint cylinder scene. Grip is also very good as revarnished with some flaking, and scattered dents and scratches. Replacement wedge screw. Mechanically fine.
