Puzzling Filipino (?) bolo

[drac2k]

Great Bolo!
Now let me play detective as well. I believe what you see are the remains of scotch tape that covered a descriptive label about the item; over the years the tape yellowed. The tag was removed with the tape and thus you have the brass colored perimeter where the tape was left; the tag may even be the one now on the scabbard. Measure it and see if it fits.
