OK, great, thank you! The stock has no marks on the nose. The only stamps I can make out other than the AAP are what looks like a faint "F" to the left of the AAP, a number "4" in front of the magazine floorplate, a "36" on the bottom of the toe of the stock behind the rear sling mount (rack number?), and the stamps on the wrist by the stock repair (a circle "P", and number "7", and something that's been obliterated by the screw). ETA: Missed what looks like an "O" stamp in the cutoff recess.
Could that stock repair have happened at Augusta Arsenal? The Arsenal stock repairs I see are so much cleaner, I immediately assume that's a home job, but the repair is old and I see mentions of brass screws being used by armorers...here's a picture of the split from the side.

So leave it be, or is it a candidate for a talented gunsmith to do a cleaner repair?
Again, my knowledge on the subject is no deeper than a few hours of reading online resources and forum posts. My hopeful theory was based on this:
1. I understand the serial number is in the range of RIA receivers that were shipped to Springfield and completed as rifles in 1928ish.
2. Those rifles would be completed with 1927-dated SA barrels - check.
3. The punch prick in the ordnance bomb on the barrel indicated a barrel that had been proof-tested as part of an assembled rifle.
I've never fired this rifle as I wasn't sure about the stock. Doing a safe clean-out and I'm trying to decide whether to hold on to it, correct some parts, shoot it, get another 1903 as a shooter, push it down the road if it's just a gun with a couple desirable parts...
