New 1903A3 - Can anyone with more knowledge tell me more about this example?

[Tom in N.J.]

All M1903A3 rifles left the factory with a straight stock, as shown on a M1903 in RTL's second photo. Remington M1903A4s were at first issued with a "C" type stock furnished by Springfield Armory and modified for the bolt relief by Remington. The majority of M1903A4s had "scant' stocks (with a pistol grip) furnished by contractors, and modified by Remington. Smith-Carona M1903A3s all had sub-contractor furnished straight stocks.
