Manufactured in 1918, it is listed on p. 520 of "U.S. Military Automatic Pistols 1894-1920" by Meadows as being part of a shipment of 20 pistols to the ordnance inspector at Winchester Repeating Arms Company on 26 April 1918, shortly before the end of World War I. These pistols would have likely been used for testing Winchester manufactured ammunition, however, judging by the exceptional condition of this example, it was never selected to be used. The left side of the slide is marked with the standard two-line, two-block patent dates and address on either side of the Rampant Colt, while the right side has the standard model and U.S. army marking. The left of the frame has the standard U.S. property marking and a "JMG" inspector marking. The blued barrel is marked with a conjoined "HP" on the chamber hood, "Z" on the right of the lug, and "5" in front of the lug. The two tone magazine is unmarked and has a lanyard loop base. It is fitted with diamond pattern checkered walnut grips.

Excellent, retains 97% plus of the original brush blue finish with a few scattered light dings showing bright and a very light takedown mark on the left of the frame. The grips are equally excellent with only the slightest handling marks and crisp checkering. Mechanically excellent. An outstanding example of a U.S. Colt Model 1911 that was shipped to Winchester!
