This is an original example of a U.S. inspected Colt Service Model Ace that was produced circa 1941. The left side of the slide has standard Colt's two-line patent dates and Colt Hartford address in two unbroken lines followed by the Rampant Colt logo. The right side of the slide is stamped with standard "Colt (followed by) SERVICE/MODEL ACE (inside a diamond logo) .22 LONG /RIFLE". The slide is correctly not serial numbered to the receiver. The left side of the frame is stamped with the boxed "WB" cartouche of the U.S. Ordnance inspector Col. Waldemar Broberg, however the frame is not stamped with the usual U.S. Ordnance Corps Cross-Cannon proof nor the "UNITED STATES PROPERTY" markings, which may indicate its an overrun frame that was used for commercial production. This example does have the pre-war type adjustable target rear sight matched with the high, thick blade front sight. It is also fitted with the fully checkered walnut stock, milled trigger with he checkered face, checkered main spring housing, thumb safety and slide stop release. It has the wide spur hammer with the borderless checkering. It comes with one original Colt ACE half-tone magazine that is marked on the floor plate: "COLT/22 ACE L.R./SERVICE MODEL.".

Very fine with 85% plus of the original blued finish showing only minor edge and high spot wear with blue loss on the front edges of the slide, with some thinning/browning on the main spring housing. The grips are in excellent condition with nice sharp distinct checkering overall. A really nice, high condition early/pre-war Colt service Model Ace pistol.
