This revolver was manufactured in the Colt London factory in 1855 and was used to arm the Canadian militia under the Adjutant-General of Militia's order on May 16, 1856, specifying that "Each Cavalry Volunteer will receive one cavalry sword with scabbard complete, one six shooting Colt's pistol, one sword belt, one sword knot, one cartouche box and one holster, one cleaning rod, and one nipple wrench." In the mid-1850s, Canada was bolstering its militia forces due to United Kingdom's involvement in the Crimean War which had dramatically reduced the number of soldiers stationed within Canada, but the force was still fairly small at 5,000 active volunteers. The revolver has the "-ADDRESS. COL. COLT. LONDON-" barrel address, London proof marks on the barrel and cylinder, "COLTS/PATENT" on the left side of the frame, matching serial numbers, the standard cylinder scene, varnished walnut grip, and rounded head screws. "U.C/G/23" is marked upside down on the left side of the grip which indicates this revolver was issued to the Upper Canada Militia, Troop G, Trooper 23.

Very good plus with 30% original case colors, 20% original blue, gray and brown patina on the balance, some mild scratches and dings, minor pitting, and general mild overall wear. The grip is fine and has crisp markings, glossy varnish, mild edge wear, and some dings concentrated on the right side of the butt. Mechanically excellent.
