Can anyone ID this axe? Weapon? Tool? Origin? Age?

Mods, if this needs to be moved please do so. I don't really know where to post it.

This axe is a mystery- I have asked in different forums, and among private axe collectors with much experience. No one has a clue as to origin or age.

5.4 lbs, cutting edge 5 3/8", length 8", thickness 1 11/16. Poll 1 1/4" dia.

It seems too massive and heavy for a weapon, and too decorated for a tool.
On the thick side for a wood cutting axe, and about right for a splitting axe.
