I have to agree with Kai and Battara on their dating of this ensemble to the late 20th C. It is possible the blade is older, but the carving on the hilt and scabbard point to a recent date. The ornate horn
kakatua is well done, and I like how it flows from beak to crest. The earliest date I have seen attributed to this style is around 1990.
The blade shows forward-weighting, with the widest part occurring on the tip side of the halfway point down the blade. [I don't think we need to draw lines to see that is the case.] This is a similar geometry to a recently posted
barung discussed
here and considered to be Yakan. In my experience the Yakan and Maranao
barung share this feature, which differs from the
barung of the Sulu Archipelago.
