Definitely Yakan, as already mentioned.
A nice older example from the 19th C. judging by its appearance. Very hard to find the truly old ones, although pira in the older style are still being made. Most of the traditional style pira that we see are post-1920, according to my sources in Manila.
Cato says the pira is used almost exclusively by the Yakan, and my Filipino sources say the same thing.
