In May of 1942 the U.S. government initially placed an order with Union Switch & Signal Co. for 200,000 Model 1911A1 pistols, an order which was later revised to 55,000 pistols. This pistol was likely manufactured early to mid-1943. The slide is marked with the "USS" monogram and "U.S. & S. CO./SWISSVALE, PA. U.S.A." on the left side, with a Robert Downie "R.C.D." on the left of the frame, and standard U.S. government nomenclature on the right. The full blue barrel is marked "HS" and "P" on the lug. It is fitted with blade and notch sights, thin checkered hammer, short stamped trigger, long grip safety, arched checkered mainspring housing with lanyard loop, Keyes Fiber checkered grips (one has grip screw escutcheons, the other doesn't), and a full blue "S" marked magazine.

Very fine, the slide retains 97% plus of the original parkerized finish with a few small patches of light pitting/oxidation on the front right and some light edge wear. The frame retains 95% plus of the factory presentation blue finish with some light edge wear. The grips are very fine with a few scattered minor blemishes in the otherwise crisp checkering. Mechanically excellent.
