Hola Carlos
Looks like you have a nice catch there!
It looks like a barong to me, too. Am not sure however from which part of Moroland it would be coming from.
Talking about barongs originating from southern Palawan (which as early as the time when Magellan landed in the Philippines (1521) up to now, are inhabited by Muslims), a fellow Filipino and a member of this forum sold me earlier two southern Palawan Moro barongs (photos below).
They are not that old to be classified as antiques. Just the same, the make is of very good quality, and we may note that the blade is somewhat elongated, too.
