This rare Model 1911A1 "demonstration pistol" was manufactured by Remington Rand in 1943. These "demonstration pistols" were manufactured to show employees the finished Model 1911A1 pistol, explain how it was used, and emphasize the importance of every aspect of manufacturing in the functioning of the pistol as a whole. Remington Rand manufactured only 145 demonstration pistols in a separate series beginning with serial number "1". The pistols had a parkerized finish and the serial numbers were stamped on the pistols after it was applied. The pistols did not have military nomenclature, inspection, proof, or "U.S. Property" marks on the slide and frame. After the war, these pistols were subsequently presented to Remington Rand officials and employees. These pistols are described on page 313 of "Colt .45 Service Pistols: Models of 1911 and 1911A1" by Clawson and an example, serial number 131, is pictured on page 314. The only visible markings on the pistol are "REMINGTON RAND INC./SYRACUSE. N.Y. U.S.A." on the left of the slide and serial number "57" on the right of the frame. It is fitted with blade and notch sights, short stamped trigger, narrow checkered hammer, long grip safety, a serrated arched mainspring housing, lanyard loop, checkered Keyes Fibre grips, and an "S" marked full blue magazine.
