ID need of man with spear

[Nonoy Tan]

Here is an old photo of a man holding a spear, supposedly taken in the year 1870. Can somebody ID the probable ethnic backgroud of the man on the basis of the spear (or scarification on his body)?

The photo indicates "moro". Is this a misnomer?

The curly hair may indicate that this man was of negrito descent. If indeed he was moro (i.e. from Mindanao), has anybody read about negritos fighting for the moros (or moros emploring negrito men for war)?

Thanks,

Nonoy
