African spear

[Kmaddock]

Hello
I picked up this spear at a local car boot sale
I was told it was zulu but obviously not as it is socket attached rather than tang attached to shaft
I looks to have age and as you can see from the last picture my son liked it so I bought it
I am thinking it is from Congo from my back post searching but would anyone be able to confirm this
also do you think it is a large animal hunting spear?
Best regards
Ken
