I was just reading an article that stated after 1943 there was no longer a need to mark axe heads with "U.S. Army". I think that might have been for the one particular manufacturer. I can see markign generized military equipment with US and imagine it is a military owned/issued item. Date? No clue...
Hi Professor, I have a head similar to the one you pictured. What if any is stamped on the other side of your ax head? Mine has lettering but is to pitted to read.
