The pre-16th C. Philippine gun ("baril")

[migueldiaz]

from san antonio's 1624 filipino[tagalog]-spanish dictionary:

ASTINGGAL. pc. Cierto genero de arcabuz de que estos usaban antiguamente, viene de Burney [Borneo], es como pieza.

BARIL. (l. Badil HM [Hanunuo Mangyan]) pc. Cualquier pieza que lleva polvora

PONGLO. pc. Pelota, o bala de alcabuz, o el acto de cargar con ellas.

to this day, we in manila still use 'baril' to refer to any firearm, and 'ponglo/punglo' to refer to the cartridge. 'astinggal' is not used anymore.

kindly note that the author thought that the philippine firearm came from borneo/brunei. hence it will be very helpful if we can see what a 16th century bornean firearm looked like ...
