Hi David,
The flanges holding the blade look like they were crudely repaired at some point, and it's odd that they do not align with the blade. The gauntlet looks a bit like a khukri I once posted, that had been aged and dunked into bronze of some sort. The monster head i've seen on a number of patas, so I don't think that's unusual. There is another one I'm watching on the bay, perhaps the bidding will not get as rich
