Throwing Spear

[Winnlex]

I am trying to get information on a throwing spear. I do not know its origin/history. I believe my dad got it many years ago. It's about 6ft long. Can anyone point me in the right direction? Any help will be appreciated. Thank you.

To my eyes this looks like a budiak, a Moro spear from the southwestern Philippines. Not sure of which tribe however.
