your serial number dates to 1927, it would have been one of the last 1903s made before the A1 standard was finalized. beyond that I have not the slightest clue as to how to determine whether it was a national match.
one thing I would like to mention is that even if it was for the army marksmanship team, the removed decocker peice should still have been parkerized with the rest of the gun. everything on your gun has been blued, not parked and the removed decocker is white, leaving me to believe that this little modification was done by Feren, not by USOD.
ignore my complete lack of capitalization. I still have no problem correcting your grammar.
