The Colt Single Action Army was one of the most popular handguns in late 19th century and is easily the most iconic and most thoroughly associated with the American West. This example was manufactured in 1890, and it certainly has the classic look of an authentic cowboy gun, as well as having been shipped to one of the many St. Louis retailers known for shipping guns farther west. The barrel has the correct two-line Hartford marking on top. The left side of the frame has the two-line patent dates marking. The caliber designation "45 CAL" is stamped on the left side of the barrel. Matching serial numbers appear on the frame, trigger guard and back strap, and the loading gate has assembly number "356". The included factory letter confirms the current configuration (grips not listed) as well as shipment to E.C. Meacham Arms Co. in St. Louis on 15 November 1890.
