Looks like a vintage Estwing or Marbles type throwing axe... I doubt either of those brands, but the head shape fits the odder throwing types and the stacked leather grip and what looks to be plated pommel cap and potentially the half too, puts it in these age bracket to my eye.

If you live locally to where it was sourced, seek out an old timer who specialises in throwing sharp pointy things, they might have some insight as it is a very popular sport down that way... might be worth going over it with a magnifying glass too... given the age and the plated surface now peeling, there might be a feint makers stamp on the metal somewhere....

Edit Edit... I reached out to a friend who specialises in throwing things of all shapes and sizes... he said the handle screams custom made... and by design it is fit for purpose.
