Outstanding and Rare Documented Presentation U.S. Ithaca Model 1911A1 Semi-Automatic Pistol Serial Number I.G.50 Manufactured c. 1945, this is one of approximately 50 presentation Model 1911A1 pistols produced by the Ithaca Gun Co. after completion of their World War II government contracts that bear the special "I.G." serial number prefix standing for "Ithaca Gun". This specific pistol is pictured on p. 131 of "U.S. Military Automatic Pistols 1920-1945" by Meadows, where it is described as the last pistol of the "I.G." presentation series and the only one known to the author to bear U.S. government markings. These pistols were produced specifically for presentation to top company officials and Ordnance Department officers that played a roll in attaining and completing the government contracts that Ithaca had received. Throughout the course of the war Ithaca had received multiple contracts from the government for Model 1911A1 pistols, even though early on their quality was in question, having an alarmingly high number of pistols rejected by government inspectors. By September of 1943 Ithaca were pushed to make some changes to improve the quality of their production, which by the middle of 1944 seemed to dramatically reduce the number of Ordnance Department rejections. By the end of the war, Ithaca was the third largest producer of the Model 1911A1 pistol having made 335,466, following only Colt and Remington-Rand. This example certainly shows the culmination of learning and improvement Ithaca experienced through the course of the war, displaying a level of quality that is clearly evident. It is entirely finished in a highly polished deep blue with the only markings being the U.S. property marking, model designation, and hand engraved, presentation serial number "I.G. 50" on the right of the frame. It is fitted with blade and notch sights, short checkered trigger, long grip safety, arched serrated mainspring housing with lanyard ring, wide checkered hammer, reinforced checkered grips, and an "S" marked full blue magazine.
