Serial Number Information If you provide good photos of a pistol, with the full serial number visible, I will attempt to provide, free of charge, year of manufacture or shipment/procurement. In the Gallery I show more than (700) pistols to enable Subscribers of the site to compare pistols to the examples shown and determine year of production. Right side of Colt 1911 serial number 446933. Has heart shaped openings under grips that started at approximately serial number 375,000. Pistol also has the thick trigger guard. Note lack of UNITED STATES PROPERTY marking over serial number. A geometric-shape proofmark, like a triangle, arrowhead or such, on the front left of triggerguard indicates an M1911A1 made by Ithaca. An 'X' prefix to the serial number indicates a gun that has been re-serial numbered by ordnance, and the maker is neither identifiable or relevant. His initials will also be found on rifles and shotguns made by Remington, the 1911A1's made by Remington Rand and military vehicles. The 1911A1 Ithaca pictured on this webpage is one of the 30,000 pistols that was produced in late 1943 in it's serial number range. It has a 'HS' or High Standard stamped barrel.
This M1911A1 was manufactured by the Ithaca Gun Company in late 1943 according to historical records. The M1911A1 is a recoil operated, self-loading, semi-automatic pistol that has been chambered for the .45 ACP cartridge. The pistol has been designed to operate as a single action firearm that utilizes an external hammer. The steel frame has a grey parkerized finish. The sight system includes a square blade front sight that is milled as part of the slide, and a square notch rear sight that is housed in a dovetail slot and drift adjustable for windage only. This pistol is fed by a single column 7 round detachable box magazine. The pistol utilizes a push button magazine release that is located on the frame at the bottom rear corner of the trigger guard. An empty magazine will easily eject from the pistol under its own weight. The pistol also features a thumb safety located at the rear of the frame behind the left grip panel. This sidearm weighs in at just about 2 1/2 pounds and has an overall length of 8.25 inches and a barrel length of 5.03 inches. This weapon does employ a slide hold open mechanism to inform the operator that the last round has been fired. The checkered grip panels are made of plastic and were manufactured by the Keyes Fiber Co.

John M. Browning came up with this pistol design which was formally adopted by the U. S. Army on March 29, 1911 and has been the standard issue side arm for the United States armed forces until 1985. Although the M1911A1 style of pistol is still being carried by some U.S. forces to this day.
Ithaca 1911 Serial Numbers Dates
When Ithaca started manufacturing the M1911A1 in December of 1942 the only other firm to be doing so at the time was Colt. Ithaca produced a total of about 382,000 pistols during WWII. When production started in 1942, the Ithaca company did not have the equipment to manufacturer many of the smaller parts for this pistol. As a result, they ended up receiving parts from other suppliers that included 6,200 WWI Colt receivers that Springfield Arms still had in storage along with numerous small components.
During the manufacturing process, a gentleman by the name of Harry Howland whom was employed by the Ithaca company designed a stamped trigger assembly which was later approved by the Ordnance Department. This stamped trigger assembly became known as the Yawman Trigger due to the fact that it was fabricated by the Yawman Metal Products Co. of Rochester N.Y. During any conflict and especially during a world war every one involved tries to produce weapons as fast as possible and as cheap as possible. This Yawman Trigger was said to reduce the cost of the 1911A1 by 5 percent. Maybe Ithaca had these measures in mind as the pistols that they produced had the roughest finish of any of the 1911A1's produced during the war even though the company manufactured fine shotguns before WWII.

Our Assessment: This is a U.S. Government marked Ithaca Model 1911 A1 pistol made in 1943 during WWII. It is in about Fine condition with a thinning on the edges of the slide and a few handling marks. It has its original finish and is correctly marked for a pistol made by Ithaca in 1943. The barrel is made by High Standard, who supplied Ithaca with barrels in that time frame. It has a great bore with sharp rifling. This pistol includes documentation on the original owner who served as a 2nd Lieutenant with the 306th Bomb Group during 1944 and went on to become a Lt. Colonel in the Air Force, and a reproduction of his Air Medal. This is a highly collectable package. Ithaca produced fewer pistols that either Colt or Remington Rand during WWII, and you don’t see very many in such good condition with the original finish. If the collectors don’t jump on this one, it will be a long time before they see another documented package of a WWII 1911A1 Ithaca in this condition.
