Please help ID these spears

[Clubs & Arrows]

Rick,
When I purchased this from the previous owner's estate, I did also pick up a Nias stool, so it is possible. One of the problems is that when I purchased the spear, it was along with a lot of Philippine, Oceanic, African, and other Southeast Asian material. Kind of an ethnographic mixed bag. I'll certainly start looking towards Nias to see if I can find anything similar.

Thanks again,
Joe
