Hi, my name isXXXXX would be glad to help you any way that I can by answering your question to the best of my ability.
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).
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.
The 2002 BBGV rates this gun as follows (add 10% if a Winchester manufacture): original high polish blue - 100% - $2700 . . . 98% - $2300 . . . 95% - $1900 . . . 90% - $1400 . . . 80% - $1100 . . . 70% - $850 . . . 60% - $650
