I agree: the blade looks Moro, the hilt seems to be Lumad. It's not rare to find captured/traded Moro blades as well as reproduced Moro-like blades with Lumad tribes. Their kampilans tend to be quite small though and I haven't seen any blade coming close to a full-sized Moro kampilan. Seems like someone needed a large stick...
Please post some more pics of the hilt, Jeff.
