I have several like this; a couple are even hafted. No indication on any of them as to who, what, when, and where they were made. I have always just assumed that they were frontier made in the East during the 1700s to mid 1800s for the Indian trade, or pioneer use. Lots of fakes out there apparently. I bought two heads from Jim Dressler, and have never questioned their authenticity. This one looks totally right and it's nice to see it with a handle. Doesn't happen all that often given all that hard use back then.
There is a trade axe website that gives some information, but not sure that everything presented is correct. Thank you for bringing your nice find here, and if you learn more, please share it with us folks.
