This piece is most likely from Davao City or thereabouts--a major melting pot for Visayan/Lumad/Moro cultural influences. After market treatments may well have occurred in the U.S. A major fraction of the population of Davao City are Visayans.
It is uncommon but not rare to see T'boli hilts on Moro weapons--I have several
kris and "
kris-like" swords with T'boli hilts and scabbards. Similarly, Bagobo hilts on Moro weapons are also found with some frequency, especially coming through Davao City and neighboring areas.
The topic of this thread appears to be T'boli/Visayan to me, and I don't see much Moro influence apart from the
kakatua hilt which is T'boli in origin and well made (many of these hilts were carved in wax by women). It might well be a custom-made piece. I doubt that it is older than mid-20th C.--most of these cross-cultural pieces made for commercial purposes seem to have been produced post-WWII.

BTW, Diltiazem is used for treating hypertension and heart problems
