You have a so-called NRA Sales rifle - they were sold to NRA members from about 1910 to 1916. They are probably the largest group of "unmolested" pre-WWI M1903 rifles in existence. They are rarely listed on SRS. Note the "NRA" stamp on the forward tang of the trigger guard. The purpose for this stamp was to make the rifles identifiable if they were sold to a third party (which they weren't supposed to be done).
Your rifle appears to be completely original, although it has obviously received a fair amount of use. I have three of them and they are among my favorites. Pre-WWI M1903s, IMHO, are works of art!
