Hello Jose,
Thanks for the classification.
Maguindanao and early 20th century was also my guess but i was unsure because of the pommel and the "chopsticks" on the hilt.
The wooden sticks seem to be purely decorative as the asang-asang are fastened by copper bands that go below the metal fittings of the hilt.
I vaguely remember having seen a similar construction with just one wooden stick on a barong but i cannot find the picture anymore.
Best Regards,
Thilo
