a selected group of army officers and congressmen. After firing several rounds from what appeared to be an unmodified Springfield, he removed the standard bolt, inserted the device, and fired several magazines at a very high rate of fire. The evaluation team was favorably impressed. To deceive the enemy, the Ordnance Department decided to call it the US Automatic Pistol, Caliber .30, Model of 1918. Plans were put into place to start production of modified Springfields, which became the US Rifle, Cal. .30, Model of M1903, Mark I. The Army placed orders for 133,450 devices and 800,000,000 cartridges for the 1919 Spring Offensive. General John J. Pershing requested 40 magazines and 5000 rounds of ammunition be shipped with each device and anticipated an average daily ammunition use of 100 rounds per device. The use of the Pedersen device in the 1919 spring offensive was to be in conjunction with the full combat introduction of the M1918 Browning Automatic Rifle (BAR). The US Patent Office issued , , , and to Pedersen for his invention. The United States Army paid Pedersen $50,000 for rights to produce the device and a royalty of 50 cents for each device manufactured. The Army paid for all necessary machinery required to manufacture the device, and Remington received a net profit of two dollars for each device and 3 cents for each magazine. A Mark II Pedersen Device was also designed for the M1917 "American Enfield" and a similar prototype was made for the Remington-produced Mosin–Nagant; neither of those were ever put into production. Production Production of the device started in 1918, along with the modified rifle that December, after the war ended. The contract was cancelled on 1 March 1919 after production of 65,000 devices with 1.6 million magazines, 65 million cartridges and 101,775 modified Springfield rifles. Each device was to be issued with a belt including a stamped, sheet-steel scabbard for safely carrying the device when not in use, a canvas pouch to hold the M1903 rifle bolt when not in use, and canvas pouches holding five magazines. The device with two pouches of loaded magazines added 14 pounds to the infantryman's standard load. Remington subcontracted magazine production to Mount Vernon Silversmiths, and the carrying scabbards were manufactured by Gorham Manufacturing Company. Canvas pouches for magazines and for the rifle bolt were manufactured at Rock Island Arsenal. Ammunition was packaged in 40-round boxes sufficient
