Uhhhhh..... Let's say kayan, because it looks like a hilt that Mjoberg describes as Kayan in his book "Borneo"

I am not sure if you could either pinpoint it on kenyah or Kayan as these tribes are very close to each other, and that is also a guess.

But it is a very nice example and a very good start for a mandau collection
