The First Model Dragoon is an important descendant of the famous Colt Walker revolver which debuted just one year earlier. These revolvers were designed for mounted use by the U.S. Mounted Riflemen and 1st and 2nd U.S. Dragoons in the antebellum era and were also popular in the American Southwest. They saw use during the American Civil War in both Union and Confederate hands. This revolver was manufactured in 1849 and has the distinctive first model cylinder with oval cylinder stops like the Walker along with a squareback trigger guard as well as the subtler First Model hammer and mainspring. The upper barrel flat is marked "-ADDRESS SAML COLT NEW-YORK CITY-" reading from muzzle the towards the breech . The left side of the frame is marked "COLT'S/PATENT/U.S." Single letter inspection marks on various components. No cartouches visible on the grip. Matching serial numbers are located on the barrel, frame, trigger guard, butt, loading lever, wedge, cylinder and cylinder pin.
