For the archives, I think I found something similar to this sword (while searching for a different type of Mandara short sword...), though we would need to require unsheathed pictures from the museum to be sure.
Anyway, very similar scabbard, grip, and pommel, same origin (Cameroon), though it seems like it was collected way more South than the Mandara mountains (but blades do travel, I noticed something similar while studying Dìì swords).
