Freddy I have looked at those pictures, I think they help a little, even if the Fulani chaps have modern versions. The Sahel is a massive strip across the African continent. At one time purloined by the French and British. I would think this spear is from the British controlled regions which would suggest a Fulani origin. I do not think these are Hausa pieces. There again things were traded so they could well have been used by the Tuareg but I do not think they are of western Tuareg origin. Now where is that Manding knife?????
