I bought this pristine 1911A1 .45 pistol from a fellow collector over 20 years ago. It is a Colt manufactured version and by the serial number it was made sometime in 1942. It is early enough in the Colt production that the serial number is also stamped on the slide under the firing pin retainer plate. They stopped doing this later in the production series. All indications are that this pistol was never fired, which the prior owner also believed.
The group picture is the pistol along with some mint WWII web gear, holsters and accessories. The M7 shoulder holster is a BOYT made, USMC marked and 1945 dated.
