definitely an older barung, sulu, 19th c. handle is bunti. as far as if it was owned by a wealthier moro, it's hard to say. perhaps. if you have the book Moro Swords by cato, and turn to page 6, there's a gentleman, second to left posing with his barung. tho it looks ordinary and not the junggayan type, it's still a datu's barung, considering that gentleman is the brother of the sultan.
as far as fixing it, this thread might help you out...
