With regard to markings, on the right side of the barrel, just in front of the receiver, there are three marks. One kind of looks like an arrow pointing toward the muzzle, then there is REP is circle/oval, and the number 13.
On the left side, there are 3 more. One is, in small print, 308 win, then a Y, and then, closest to the receiver, CM.
I will take some close ups of the marks and if you'd like to see them, please PM me your email address.
Thanks.
