Enfield, P-17 (Pattern 1917) Rifle, .30/06 bolt action, Serial No 135830, Seaforth Highlanders of Canada 2nd Reserve Battalion used this type in WW II, usually with a red band painted near the muzzle to signify .30/06 calibre. PARTS REMOVED FOR SECURITY (PR) The M1917 Enfield, the "American Enfield" (frequently misidentified or mislabeled as the "P17", "P1917", or "Pattern 1917"), formally named "United States Rifle, cal .30, Model of 1917" was an American modification and production of the British .303 caliber P14 rifle (listed in British Service as Rifle No. 3) developed and manufactured during the period 1917-1918. As it entered World War I, the UK had an urgent need for rifles, and contracts 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 caliber for convenience of supply. 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" and "Eddystone".
