Manufactured in 1945. The factory letter indicates it was part of a 745 gun shipment sent to the Transportation Officer at the Springfield Armory Ordnance Depot on September 18, 1945, with a .22 caliber 5 inch barrel, adjustable rear sight, "Parco-Lubrite" finish, and molded plastic grips. The remarks state that it was "Packed in Case No. 251. Colt Factory Order 5078. Contract W19-059-ord-2375." It features: blade front and adjustable rear sights, the two-line address and patent markings on the left side of the slide, "COLT SERVICE/MODEL <ACE> .22 LONG/RIFLE" on the right, "JSB" (John S. Begley) inspected frame, "UNITED STATES PROPERTY" above the serial number, checkered thin hammer, stamped trigger and thumb safety, long grip safety, serrated slide catch, arched mainspring housing, reinforced Keyes Fiber grips, and a full blue Service Model magazine.

Very fine overall with 85% of the original Parko-Lubrite finish, a mixed gray patina on the grip straps, bright edge wear, and scattered light spotting and handling marks. The grips have some light dings. Mechanically excellent.
