Produced in 1918, and later arsenal overhauled and has a gray parkerized finish. Fixed sights, with the two line Colt patent dates, Rampant Colt and two line Hartford address on the left side of the slide, and "P" on top. The frame is marked "UNITED STATES PROPERTY" over the serial number on the right side, with an "eagle head/ 6" on the left. Equipped with a wide checkered hammer, short grip safety, long milled trigger, reinforced Colt wood grips and a "COLT 45 AUTO/ P" marked barrel. Included with the gun is an extra Remington-Rand slide, inscribed on the right side "SGT.F.P.Williamson", and a "S P" marked barrel.

Very fine arsenal refurbished, showing 99% of the current parkerization, with scattered light handling marks and some pitting visible underneath the finish. Grips are excellent arsenal replacements, with pressure dents and scuffs. Extra slide has 90% parkerization, with scattered wear and handling marks. Mechanically excellent.
