Battara, I'm confused (which is not something new)
I had thought that all that filigree work came out of Central Mindanao.
All the previous kris that I've seen provenanced to Sulu had generally smaller blades, though I agree this blade looks Sulu (especially the eagle beaks slant) and that they generally had the horsehoof handle. Granted there are many exceptions and I've seen that small pommel on many, but I've not seen that filigree on any blade attributed to Sulu.
Could this have been an old Sulu blade and pommel that was redressed in the Central Mindanao style? I've seen several of that type (and own one) in many of the antique shops in the PI.
