I will get more pics later but figured this could get the ball rolling. The USA was stamped over what looks to me like the mark TG. I found the TG mark online but no good info on it. There’s one on the auction site that’s the same size/shape and has the TG mark. But no USA mark.
Also, inside the eye, 1/4 inch down on each side it has steps running front to back. I am thinking they give the wood something to bite in to when the wedge is driven in. They are1/64th -1/32 inch
