I'd Like to Learn More About This Visayan Sword

[CharlesS]

Here is what I assume to be a Visayan sword. It has a typical Visayan convex/flat blade and a lovely carved scabbard with a leather mouth cover in the Visayan style. The hilt, to my eye, is way "over the top" in its monster motif and I am not familiar with it.

I'd appreciate any input and info on it.

Dimensions:

Overall length: 28.25in.
Blade length: 20in.
Blade's widest point: 20in.
