Dayak ? hat for ID

[colin henshaw]

Hi

This is a recent acquisition. Not a weapon, although its quite strong and rigid so might serve as head protection of a kind. There are a number of collectors and experts of South East Asian material on the forum, so can anyone kindly help out with identification ?

I am thinking maybe Dayak, with the beadwork over the plaited fibre, or perhaps elsewhere in that region...

Ideas on identification, comments and references welcome. Thanks in advance.
