Origin of this spear head

[danny1976]

Hi Willem And Vandoo,

I picked up the lance yesterday and did made some extra pictures.
Still not clear where it comes from but like Willem suggested it looks like it is from Celebes .In the database from Rmv i find Lance's with similair construction and also in the book from Zonneveld .

Total lenght is 218 cm.
The point is heavy and nicely forged, on the end there is missing a endcap.
