keris, siraui or somethingg else?

I agree. It certainly is not a keris, even though it does have a keris hilt. The hilt may be a replacement, though i don't know what the orginal may have looked like. Nor is it a siraui, which does curve similar to this, but is a single sided blade. Detlef may be correct to place this in the kerambit family.
