Crowns on Aceh weapons revisited

[asomotif]

I go to Bronbeek quite often but cannot remember seeing this baby?

Hi Erik, I assume they wil not have all Atjeh weapons on display.
This is another picture from this article by the former head collection of Bronbeek, Dirk Staats. (notice the Kupiah)

This rentjong with the forked handle, with the incissions and also the rare type of crown + inlays is indeed something I have not seen before.
It would be intersting to know if Bronbeek has provenance on their pieces.
