Manufactured in 1913, the second year of production for the U.S. contract Colt Model 1911 pistol. It is listed on p. 516 of "U.S. Military Automatic Pistols: 1894-1920" by Meadows as being included in a 600 gun shipment to Springfield Armory on 10 December 1913. The serial number is marked on the right of the frame above the trigger guard and the left side has the U.S. property marking and the "WGP" inspection mark. The slide has the two-line, two-block patent dates and address on the left with the Rampant Colt behind the slide serrations and the model and army nomenclature on the right. The full blue barrel is marked "5" on the bottom, "J" on the left of the lug, and "P H" on the chamber hood. It has blade front and the correct early round-top notch rear sight, which were beginning to be phased out in 1913. It is fitted with a long smooth trigger, checkered slide release and thumb safety, short grip safety, wide checkered hammer, and a smooth straight mainspring housing with a lanyard loop on the base. The grips are diamond pattern checkered and the magazine is a two-tone, later replacement. Includes a "US" marked leather swivel holster which is hand marked inside the flap "Col. R.C. Langdon [illegible]/U.S. Army". A colonel Russell C. Langdon is listed as being awarded the Distinguished Service Cross during World War I along with an Army Distinguished Service Medal, as well as a Silver Star for gallantry in action during the Santiago, Cuba campaign in 1898. Also includes an American Red Cross canvas bag, two lanyards, and seven extra magazines of varying style.
