Ok I now have this!
It showed up here in Louisville, KY last month. I cleaned it up and here are the pictures.
Dimasalang, I hope you are at least a little happy - a pinoy has it now and has posted it here for research......
Here are the pictures of the front, the blade, the back, the top, and the quillions. All of this is engraved silver. The top nut is screwed onto the tang that goes through the hilt. Also the hilt is albino carabao horn with silver nails.
