French blades on Saharan Edged Weapons

[Jerseyman]

Not sure if this item fits the topic, but I've always assumed it was a European bayonet re-hilted for local use. I think it's camel bone, or at least the same bone as on a Sudanese Haladie in my collection. Not a great picture unfortunately as it's just an archive photo, so no stats to post. The pommel cap is brass if I remember correctly, and the underside of the blade is flat rather than concave.
