Distance? How well can you see the sights?
Per Brophy, DAL was an inspector at Springfield 1917-1918. Lends credence to my suspicion that your stock wasn't installed at the Armory, for whatever reason. That doesn't necessarily detract from the gun as 80-90% of the '03's out there are mixmasters, whether done by civilians after the fact, or by gov't operators during rebuilds. Even if all the components of a Springfield are "correct" per type and serial number year, there's no way to guarantee 100% authenticity unless it was acquired from an honest Joe who bought it new through the NRA/DCM and then stuck it in a closet for 90 years. Educated guesses can be made that may very well (probably) be accurate, but that's as far as it goes.
O Caveat Emptor when it comes to buying these things. One small example: I have a beautiful 1930-vintage 1903A1 with a minty barrel with a 1929 date. Perfectly plausible that the Armory assembled the rifle with a barrel from the year before, warehousing anomalies being the explanation. But, I know it's "incorrect" because I put the barrel on it.
