Michael:
I'm confident your sword is not Bagobo. Apart from the fat bellied blade, it has no features of Bagobo work and the scabbard is wrong.
I'm going to suggest N. Borneo for this one, primarily because of the blade decoration. An old thread on the previous Forum included examples of N. Borneo blades that had similar dot designs. These were recently made blades for the most part, but they seem to resemble the designs on your blade. That thread is here:

John might have some further thoughts.
Ian.
P.S. Does that disk guard look a little like the guard on a pakayun?
