Hey Spunjer, nice to see you back from vaca.
That kris looks familiar. Is it the one you got for Harold with the pommel repaired. If so it's nice to see it restored.
I think a lot of us would like to see a Moro weapon from the 14th century or be able to say with any amount of certainty just when the kris first appeared there. The earliest kris that Cato shows he dates to 18th century. It is, of course, possible that these "archaic" kris are a bit older. Maybe 16th century...a real stretch, i'd say, to place them any older.
I don't know how long the word "turko" has been in usage, but i think that your idea that it was introduced by the Spanish is a strong one.
Nice to have you back.
