Manufactured in 1861, the first year of production. The top of the barrel is marked "ADDRESS COL SAML COLT NEW - YORK U.S. AMERICA", "COLTS/PATENT on the left side of the frame, and "36 CAL" on the left trigger guard shoulder. The 1850 patent date is stamped in one of the cylinder flutes. The matching serial number is on the barrel, frame, trigger guard, back strap, wedge, cylinder and arbor pin. The loading lever is un-numbered.

Very good as period replated. The revolver retains 95% nickel finish with some minor pitting on the left side of the frame and bottom of the barrel lug, as well as some very minor flaking. The grip is fine with some lower edge wear, and some scattered minor dents and dings. The markings are crisp and clear. The action is excellent.
