So I saw this blade for about $5 (in USD) I think...
and I recognized the shape immediately! And of course, I bought it.
It's a relatively unremarkable blade, not very thick, long, has that characteristic spike, lines on the tang, and an interesting golden dot near the base. But despite it's plain-ness, I still wonder and have questions...
Could the dot be a brass or bronze insert? What is it for? The lines on the tang - why? The small bumps on the spike, what do they mean? Where do you guys think this kampilan blade is from? Mindanao? Timor? Sulawesi? How old? Before WW2? Post-WW2? A couple years ago? 
Here's some pictures, hope to take better ones tomorrow...
