for the new rifle were placed with arms companies in the United States. They decided to ask these companies to produce the new rifle design in the old .303 British chambering for convenience of ammunition logistics. The new rifle was termed the "Pattern 14". In the case of the P14 rifle, Winchester and Remington were selected. A third manufacturer, Eddystone Arsenal – a subsidiary of Remington – was tooled up at the Baldwin Locomotive Works in Eddystone, Pennsylvania. Thus, three variations of the P14 and M1917 exist, labeled "Winchester," "Remington" or "Eddystone". World War I When the U.S. entered the war, it had a similar need for rifles. The Springfield Armory had delivered approximately 843,000 M1903 Springfield rifles, but due to the difficulties in production, rather than re-tool the Pattern 14 factories to produce the standard U.S. rifle, the M1903 Springfield, it was realized that it would be much quicker to adapt the British design. Although it might have been faster to retain chambering for the .303 British military cartridge, the design was modified for the U.S. .30-06 Springfield cartridge to simplify ammunition logistics. The Enfield design was well-suited to the .30-06 Springfield; it was a big, strong action and was originally intended to employ a long, powerful, rimless bottlenecked cartridge. Accordingly, Remington Arms Co. altered the design for caliber .30-06 Springfield, under the close supervision of the U.S. Army Ordnance Department, which was formally adopted as the U.S. Rifle, Caliber .30, Model of 1917. In addition to Remington's production at Ilion, New York and Eddystone, Pennsylvania, Winchester produced the rifle at their New Haven, Connecticut plant, a combined total more than twice the 1903's production, and was the unofficial service rifle. Eddystone made 1,181,908 rifles – more than the production of Remington (545,541 rifles) and Winchester (465,980 rifles) combined. Although standardization with interchangeable parts was intended, early Winchester rifles (including the first five-thousand with a simple W on the receiver rather than Winchester) used slightly differing parts, causing interchangeability issues with the rifles produced by Remington and Eddystone until Winchester corrected the problem in later production. Design changes were few; the stripper clip feed, internal box magazine, bolt face, chamber and rifling dimensions were altered to suit the .30-06 Springfield cartridge and the US pattern 5-round stripper clips, the stock was slightly redesigned, lightening it somewhat, and the volley fire sights on the left side of the weapon were
