Manufactured in 1945, within the final blocks of serial numbers reported shipped to Springfield Armory in August and September of 1945, the final bulk deliveries of the Colt 1911A1 to the United States Army. An attempt was made to document the pistol via the Colt archivist (response letter included), but the search for a shipping record came back "unavailable records". An unsigned note in the barrel of the pistol suggests that this was a "tool room model", of the sort that would be retained by the factory for reference or archival reasons; the very high condition, absence of military inspection marks, and lack of shipping data lend weight to the suggestion. Blade front and flat top rear sights, with the two-line, two-block markings divided by the Rampant Colt on the left side of the slide, and a frame that bears the standard nomenclature, but is unproofed aside from the "P" on the left side; no Colt "VP", no inspector number, and no Army Ordnance initials. Fitted with a wide checkered hammer, short milled trigger, long grip safety, arched checkered mainspring housing, reinforced Colt grips, full blue "R"/"C-R" magazine, and a full blue barrel and bushing.
