Hello,
This is the 3rd barung that I had restored. It was bought without its scabbard. 
Tausug: late 19th century
OAL: 22.25 inches/ blade: 13.5 inches (spine widest area at 1-cm!).  A very heavy piece.
Scabbard

new) balayong hardwood (Cassia Javanica/ java cassia/ rainbow shower tree) with ukkil. Made by an artisan/carver from Jolo.
Blade: with Chinese characters 
Saludos,
Yves
