Yowza!!! excellent pieces, bro! pretty neat that the upper bands on the the ivory pommeled junggayan are made out of gold as well. the scabbard on the same barung looks to be newer though; notice the median ridge sticking out and the toe similar to those on the WW2 types. hey, as long as the blade fits, right?
they're definitely both Sulu, no doubt, but as far as tribal affiliation
congrats!!!
