1943 Ithaca M1911A1

This Ithaca shipped in 1943 and has the Rock Island Arsenal "RIA stamp along with inspectors initials "FK" for Frank Krack stamp. Frank Krack was Assistant Foreman of the Inspection Division at RIA from September 17, 1941 until he retired on July 19th, 1946.  During that period all small arms inspected under his supervision would be stamped with his initials "FK" as well as those of the Rock Island Arsenal "RIA".This gun retains its original components and finish. There has also been observed several Colt 1911A1s that have the same RIA stampings yet retain all the original parts and finish like this early Ithaca. 

Ithaca started production in December of 1942 and was the only established firearms company to produce 1911A1s other than Colt. The total number of pistols produced by Ithaca was 335,466. In early 1942 & 1943 Ithaca did not have all the equipment necessary to manufacture the components so they received parts from other contractors that included 6,200 WWI receivers that Springfield had in storage. These early Colt receivers (frames) can be quickly identified by the cut-outs under the stocks. Colt also supplied many of the small parts. 

Ithaca received thousands of Springfield barrels, Remington Rand hammers, and other manufacturers parts and used them for early production while the continued to set up their own manufacturing process.  Harry Howland of Ithaca designed a stamped trigger assembly that was approved by the Ordnance Department.   This stamped trigger was fabricated by the Yawman Metal Products Co. of Rochester N.Y. and became known as the Yawman Trigger.  The new trigger was adopted by all other pistol manufacturers by early 1943, except Colts who changed in April of 1944.  Changing to the stamped trigger alone reduced the cost of the 1911A1 by about 5%.   Later in the war Ithaca also designed a serrated Grooved hammer as a cost reduction but none of the other manufacturers adopted it.  Ithaca pistols were probably the coarsest finished pistols of any 1911A1.  This seems puzzling since they were previously a manufacturer of sporting shotguns and as such they must have appreciated the importance of cosmetic appearance. This is a very unique and well documented pistol.
