1903-A3 need help with cartouches

[Rick the Librarian]

Most of the stampings are unknown sub-inspection stamps but there are a few I know:

1) The stock originally was mounted on a Smith-Corona, rather than a Remington. The "diamond" forward of the trigger guard, tells me this.

2) The rifle (or the rifle the stock was originally mounted) was inspected or overhauled at San Antonio Arsenal, probably during WWII. The "square p" is also evidence of this.
