Question about a stock with multiple cartouches

[TheFonz]

I found a 1942 (6 digit) M1 Garand by my house that I looking to purchase. It is has a 1942 receiver and a 46 barrel which was most likely from a rebuild. The question I have is why does the stock bear the SA over SHM cartouche above the trigger as well as a SA over R on the butt stock? The stock has the ordnance wheel next to the SA/SHM as well as a small ordnance wheel next to the proof mark.

SA/R is probably SA/NFR. The stock was probably in good shape at rebuild so was reused and re-stamped. Double-stamped stocks are not exactly unicorns, but they're not common either. Pics would be appreciated. We ALL like pics.

Here is a few pics of the stamps and receiver.

The SA over R stamp in you last picture means the rifle was rebuilt at SA. The "R" is the inspector.

Thank you for that bit of info jak. I thought the NF was missing although I wondered about the placement of the stamp. I've been playing the M1 game for over 40 years and I like it when I learn some thing new.
