Thank you Ian. Looks a little different from what I first saw. I'm not sure I agree with you on the double versus single clamp for Maguindanao and Sulu, but as I see the back edge of the ganga, the pattern I must now say does not look very Maguindanao, but also not old Sulu either.
The front of the ganga looks more like modern Sulu pieces than older ones. Hard to say for sure though.
Only thing for sure is that the scabbard is Maguindanao, but the blade now confuses me.
