Manufactured in 1939, the included factory letter confirms the pistol's configuration, including a 4 3/4 inch barrel chambered for .22 caliber, blue finish, and type of grips not listed, when sent alone in a shipment to Fred Kroner Hardware Company in La Crosse, Wisconsin, on October 31, 1939. Features fixed oval blade front and adjustable tangent rear sights, unmarked blued barrel with polished chamber hood, along with checkered slide catch, short trigger, thumb safety, wide spur hammer, and arched mainspring housing. The right of the slide bears the two-line Colt address and patent dates with Rampant Colt, with the "ACE" designation and caliber marking on the right side. The right of the frame bears the serial number, with "4" and "triangle/VP" marked on the left of the trigger guard. Fitted with a pair of checkered walnut grips and a correct two-tone blued magazine marked "COLT/ACE/22LR" on the base. Includes the original Colt maroon box with appropriate end label and matching serial number written on the underside in pencil, manual, and bore brush.

Very fine, retaining 85% plus original blue finish with minor edge wear, some thinning/silvering visible on the grip straps, a few minor patches of spotting/freckling, and minor handling marks. The grips are also very fine with a minor gouge on the left panel and crisp checkering. Mechanically excellent. The box is fine with some edge wear visible on the lid and a few tears.
