Auto Ordnance 1911 Serial Numbers

John Thompson, 1921. (George Goll) Anyone who has watched an old movie or browsed through a book on World War II will quickly recognize the familiar outline of this fine weapon. That finned barrel topped off with a Cutts compensator, the square receiver, either a drum or box magazine. The famous 'Thompson Submachine Gun.'

Although 'submachine gun' is an familiar part of today's gun owner lexicon, the word was created by the man who was responsible for bringing us this great gun. John Taliaferro Thompson was born in 1860 and graduated from West Point in the class of 1882. Upon commissioning, he entered the army in the Artillery, later transferring to the Ordnance Department in 1890. During the Spanish-American War he distinguished himself when he directed the supply of munitions at a time of near chaos in the Army's ordnance and quartermaster units. Thompson was involved in the testing and adoption of the Springfield M1903 rifle. He became famous for tests he conducted that resulted in adoption of the.

Various calibers were tested on cadavers. Later, in the slaughterhouses of Chicago, he conducted tests on beef cattle to determine the best cartridge. From these tests it was determined that the.45 was the only acceptable cartridge for a handgun and thus leading to the adoption of the Colt.45 M1911 automatic. In November 1914 he retired from the service with the intention of devoting his full time to perfecting an automatic rifle. He was to join Remington Arms Company as their Chief Engineer. There he was responsible for organizing the construction, outfitting and operation of a rifle factory at Eddystone, Pennsylvania, to produce the British Enfield rifle. In 1916 he set up another factory to produce MosinNagant rifles for the Russian Army.

When the United States entered World War I, he was recalled to active duty and was instrumental in adapting the British Enfield rifle to.30 caliber and producing it as the M1917. Promoted to brigadier general, he was responsible for the supply of small arms and ammunition to the Allied Expeditionary Force (AEF) in France and by all accounts performed these manifold tasks with the utmost efficiency. As a result, Thompson was awarded the Distinguished Service Medal.

In December 1918 he retired from the service for a second time. Thompson's primary interest remained the development of an automatic rifle. He believed an 'intermediate' automatic weapon in the ballistic class between the pistol and the rifle would be a requirement in future wars. In Thompson's mind to accomplish this end meant overcoming several obstacles. He rejected gas operation as being too complicated for a shoulder arm.

This list of obstacles nearly exhausted the then available methods of operation. He also wished to develop a system unencumbered by the patents of large firearms companies and the hefty patent license payments that came with them. Commander John Blish, U.S. Navy, had in 1915 patented a delayed blowback breech system in which a sloping metal wedge interlocked the breech block with the gun body. Under high pressure, as when the cartridge fired, the angle of the slope was such that the mating faces jammed solid.

As the pressure dropped, the faces were able to slip across each other, the wedge moved up due to the slope, and the breech unlocked. Thompson, after investigating Blish's invention, offered Blish shares in a company he was forming in exchange for the patent. Blish accepted and with the financial backing of Thomas Ryan, the Auto-Ordnance Company was founded in 1916. Thompson hired two design engineers, Theodore H. Eickhoff and Oscar V. Payne, to work on the new design. Even though Thompson was recalled to active duty, work proceeded.
