Remington Rand Model 1911A1 pistol with special "No.ERRS 81" serial number on the right side of the frame behind the slide stop hole. Remington Rand manufactured approximately 100 pistols for product improvement experiments. These pistols had the distinctive "Experimental Remington Rand Series" (ERRS) markings and serial number. Most of the "ERRS" marked pistols were eventually presented to Remington Rand officials or employees. The feed ramp is not polished. The blued barrel has the "HS" (High Standard) marking on the right side of the lug and a "P" proofmark on the right. The pistol has late style Keyes Fibre Co. checkered brown plastic grips with reinforcing rings around the screws. The pistol has a seven rib mainspring housing, flat checkered hammer with well-defined border, and serrated slide stop. The left side of the slide is roll-stamped with third style, one-inch long markings: "REMINGTON RAND INC./SYRACUSE, N.Y.U.S.A." A "P" is stamped on the top of the slide. Frame markings are limited to the special serial number; the pistol has no Ordnance proof or inspection marks or U.S. Property markings. The pistol is fitted with a full blue M.S. Little Mfg. Co. magazine. A reproduction Remington-Rand marked box is included with the lot.

Very fine with 80% of the original parkerized finish. The grips and mechanism are excellent. This is a rare Remington Rand Model 1911A1 "ERRS" pistol.
