Barung?

[tanaruz]

Hi, need some info and confirmation if this is a barung from Sulu. My father has doubts about this piece originating from Sulu. Note: the brass features (okir?) on the hilt area. And the brass and silver ring on the hilt area too.
We have noticed the design on the scabbard (throat area)- is this typical Moro? And the metal where supposedly a string/belt passes through to be fastened to one's waist.

Probable age?

Excited about this piece.

Thank u in advance,

Yves
