African spear

[mross]

I'm pretty sure this is an African spear, but that is about all. This is not my area as I know next to nothing about it. I do hope it is an Assegai. It seems to have some age to it. The point is a bit rounded but the edges are sharp. I tried to show the head the best I could along with a ruler for a size indicator. So what do you all think as to what it is and possible age? Thanks.
