I am not sure but...
Does it have "trench art" on the wood?
There are M70 owners out there who will change the furniture of their rifle to the old wood look especially the ones with marking on them, like soldier's art/symbol, etc. Then they try to rough up the finish on the metal parts to give the rifle that look.....something like battlefield pickup look.
Looks that way, but it's not...from research, it is solid American beech...Looks like laminate to me??
