It's an older, nice condition, dark stock that has seen arsenal refub. No cartouche is visible but it is double proof stamped. It does have the older thin wrist. I would say it's original to this rifle but has been sanded and refurbed by S.A.

Most of the time we are just guessing with these things, though.

Thanks for checking and letting me know. I'll go back to the books and see what i can find.
