Hi Ian , respectfully ,
#3. Guaranteed my example is a Philippine bringback from the Span Am war era . I would have to be a time traveler to know more .
One more thing , this bolo has a carabao horn hilt , what other Spanish colony had Water Buffalo , Mexico , anywhere in S.A. ?
And to add even one more detail , consider the scabbard that is shown next to the bolo .
As Meatloaf's song title says : 2 out of 3 Ain't bad .
I'll be glad to ship you this example for personal examination if you wish , just PM me .
