A Borneo Oddity

[VVV]

I don't think we will find anything like it in any museum collections, it's one of a kind.
The blade for sure is Iban and resembling a jimpul without (or with a lost crowit). The hilt is more tricky.
I don't think it is close to any of the Bidayuh hilts, but maybe it could be a bit related with the Murut sangkit,
as Maurice suggested (not the pakayun that Indy enclosed). Below are two examples as references.
But still it's not 100 %.
My guess is that, if not Murut, it is a coastal Malay Makara inspired handle.
Maybe a cross cultural combination of an Iban who became Muslim and shifted his handle?
