Going back to the topic of blades used by bolomen as documented in old photos, so far I've not stumbled into other pics.
In John Foreman's "
The Philippine Islands" (1906), there's these two photos (below) of "Christian" and "Moro" blades. But it didn't say whether these are capture pieces.
Obviously though, the center Moro sword is not a capture piece -- the photo's caption is:
Weapons of the Moros. (Left) “Bárong”; (right) “Kris”; (centre) The Sultan of Suluʼs dress sword, presented to the author by His Excellency.
The caption of the other photo is:
Bowie-knives and Weapons of the Christian Natives. Central figure—“Talibon.” The others—Bowie-knives (Sp. Bolo, Tag. Guloc).
