Thanks again Arjan. I will consider this piece as probably from the Bukit tribe until more info comes my way?

One more stylistic motif in common with these two hilts would be that "joint" in the carving that looks somewhat like a nut & bolt viewed from the top. I have never seen this on mandau hilts before either. All very interesting stuff for me. Now, if we can only figure out what these different motifs actually represent.
