[quote][/I would guess that the .303 British (A Prototype) that RemingtonArmsmade in the Model 1903-type for Great Britain, (after war was declared) WOULD BE WORTH QUITE A BIT OF MONEY......
The initial production of the Rem Model 1903's are identical to the 1903 made by Springfield Army......Very well made as good as me custom built rifles.....Probably Worth Quite A Bit......
Than as the war went on Rem had to cut minor corners to keep up with demands for production.....
During the War, TWO, 1903A3's (modified 1903)Models were made by 2 different Companies...Smith-Corona (the Type Writing Company) and Remington...... I think Smith Corona had their name stamped on the barrel.

You are confusing the 1903 with the Pattern 14 rifle produced under contract with the Brits by Remington, Eddystone, and Winchester. Remington did NOT build 1903s in WWI...the only sources were the Springfield and Rock Island arsenals.
The Pattern 14 rifle in .303 was developed into the US M1917 (NOT P17 as it is sometimes refered to) in .30/06. The P14 andM1917 are Mauser based actions, but had some design differences. They cocked on closing, and the safety was moved to the side of the receiver, rather than being on the cocking piece as in the Mausers. The 1903 was a pure Mauser copy, and the US paid Mauser a royalty on the design until WWI started.

Remington built 1903A3 rifles in WWII. There were several design changes from the 1903, all to speed production and reduce costs. Most changes involved stamped parts where they could be substituted, and quite a few were produced with two grove rifleing, instead of the original four grove.
