Mandau with twist core

[VVV]

Thanks all,

Maurice, I also would place it in ex- British North Borneo.
This means that there were contacts with Tausugs (= twist core).
Henk, in this case it wasn't at any "loppis" (= flea market)

Who can tell me more if it's a reshaped non-dayak blade and other indications?
