African Spears - Origins?

[laEspadaAncha]

So yesterday I acquired a decent-sized collection of African antiques and artifacts, including about 20 various pieces of arms and armor. Among these were several nice older shields and a half-dozen spears. I have no problems attributing the shields (and most of the swords/knives for that matter) to their respective tribal origins, but am largely clueless with regards to the spears.

Among the spears are what I would think are both throwing spears and stabbing spears. I think (the largest) one or two might be Kuba, but I just don't know. Below are photos of each (along with the other lone African spear I already owned), along with their relevant (approximate) dimensions. Please pardon the poor picture quality.

In the first photo, of the group, the tape measure is extended out to six feet, or 183 cm. Measurements for each are provided with each photo... Due to the number of images, I'll have to split this across several posts.

Thanks Lew, Tim, et al, for any and all assistance you can provide...

Rgds,

Chris
