The U.S. Model of 1917 Winchester is a Model 1917 Enfield Military Rifle manufactured from 1917 - 1918, in this case, by the Winchester Repeating Arms Company of New Haven CT.
It is a modified Mauser-type bolt action rifle chambered in 30-06. It has a 26� barrel, 5-shot box magazine, adjustable rear site, and blade front site, supported by a military type stock with a semi-pistol grip. Weight is 9.25 pounds.
It was designed after the English .303 caliber P14 Enfield (Pattern 14) that was being manufactured in the U.S at the time for the British government by three gun U.S. manufacturers: Winchester Repeating Arms Company of New Haven CT, Remington Arms Company of Ilion NY, and Remington Arms Company of DE (actually located in Eddystone PA, later the Midvale Steel & Ordnance Company).
The Remington Model 30 is a US sporting rifle of the inter-war period based on the military P14/M1917 Enfield rifle action, which was manufactured for the British and US governments during World War I.[1][2] Initial specimens used surplus military parts with some modifications in order to consume the stock of parts, though further modifications were made as production progressed and later rifles were produced from newly manufactured parts. Most early rifles were in the military .30-06 calibre used in the M1917 but it became available in a variety of chamberings. It was the first high-powered bolt-action sporting rifle produced by Remington.
In 1917, the U.S. Government contracted with these three firms to manufacture the same rifle for the U.S. armed forces, only chambered in 30-06. Over 2 million were produced, with the majority surplused (not distributed for service). None were made after WWI, but the U.S. later supplied over 1 million of this surplus of these rifles to Britain during WWII.
