posted this in the MilSurp Forum, maybe ill get an answer here.

Found some markings on my gun today, stamped into the wood on the buttstock underside, just where it meets the back of the buttstock socket. the markings are:
S L
I <- (or 1 or just a line, i dont know which)

under that there is a wedge shape, and a six-pointed star under that.

what do these mean??

You might also try www.gunboards.com they have a board on every type of military surplus rifle.
