Manufactured in 1945. Blade front and adjustable rear sights, with the two line address and patent markings on the left side of the slide and "COLT SERVICE/ MODEL <ACE> .22 LONG/ RIFLE" on the right. "JSB" (John S. Begley) inspected frame, with "UNITED STATES PROPERTY" above the serial number and "RIA" (Rock Island Arsenal) near the slide stop. Checkered thin hammer, stamped trigger and thumb safety, long grip safety, serrated slide catch and arched mainspring housing. With reinforced Keyes Fiber grips and full blue Service Model magazine.

Very fine as arsenal refurbished, with 95% of the parkerized finish, showing a few small areas of brown spotting and mild handling marks overall. The grips are very fine with some light dings on the crisp checkering. Mechanically excellent.
