I keep coming back to this thread, hoping someone has provided something. Still nada! Just my 2 cents here.... my very worthless 2 cents. The engraving on the handle seems to lack patina, does it not? I can't help but believe this is an old piece. However, I don't think it's prehistoric "old". I have a Celt with a bird engraved on it. My Celt is authentic, the bird... I sorta doubt. I have heard engraving native artifacts was popular in the 1800's. I have a gut feeling this piece was made by someone that enjoyed altering authentic artifacts, back in those days. I hope I'm wrong, and probably am. Good luck. I'll keep popping in to see what others say.
