Klewang/Bolo ID Assist?

[Conogre]

Since I'm back, I just happen to have picked up several that have me a bit stumped and thought I'd ask you gentlemen for some assistance and opinions on.
This one has an overall length of 20 1/2", an unusual 14 1/4" curved blade that's hand forged and 5/16ths of an inch thick where it enters the hilt.
The blade is tanged and pinned into a dark wooden hilt that's split open for 3/4 of it's length and wrapped with 3 thick copper bands.
The pommel end is in the form of a simple animal face that's inset with two copper eyes and a copper mouth and has an opening in the top of the head that looks like it may have held talismentic items or something in the past.
One thing I find peculiar is that both the face on the hilt and the carving od the flower on the scabbard are VERY reminiscent of childhood drawings as might be found on a refrigerator by proud parents of a five or 6 year old.
The scabbard is two pieces of a light, dark colored wood that are pierced and held together with old wire.
The entire piece appears to have substantial age to it.
If I missed anything, don't hesitate to ask.
