Spear Head Help Needed

[Robert]

Here is a spear head that I think is African in origin but I'm not quite sure. There is also a scabbard that has nothing to do with it but any comments on its possible age are also more than welcome.

Total length of spear head is 18-1/2 inches.
Blade length is 14-1/8 inches.
Blade width is 1-3/8 at widest point.
Blade thickness is slightly less than 1/8 inch.

Scabbard length is 16-3/4 inches.
Width as widest point is 2-1/4 inches.

Again thanks for any help offered.

Robert
