1907 Springfield Model 1903

[Rick the Librarian]

RCS, to be honest, I was not aware of the specific difference in the "square" P stamps, although it wouldn't surprise me. I am reasonably certain that the "square P" was used during WWII - whether the other variation dates to post-WWII, I'm not aware. Unless the rifle was being prepared to be sold through DCM, I doubt the Army would have wasted time inspecting or overhauling a low-numbered M1903 post-WWII. Of course, the stock could have been replaced by a previous civilian owner.
