W!
And all of that inlay is intact! The hilt is suassa overlay on copper in between woven silver bands.
I would say that either the some of the silver inlay is tarnished or it was mixed with a little copper to make the silver go further.
The okir/ukkil on the blade is typical Sulu and Maguindanao designs.
I would also say that this is a Maguindanao kris.
Congratulations - best of this type I've seen in years!
