Assorted African pieces for ID

[OldMcDonald]

Hello all, This is my first post on the ethnographic forum and I'm hoping a member may have some info on the following pieces. One thing I can say is that all the items have been in my family for over a hundred years.

The first one I'm not sure if it's a Bangala ceremonial sabre, one collector said it could possibly be a Ngbandi tribe sabre, whilst a weapons appraiser classed it as being from the Yokomo tribe. The length is 28" long

Second piece is a curio that I have no idea about, so any thoughts I would be grateful to hear. The grip is a stylised figure which may have some indication of it's origin. Length 8"

Third one has been described as a Songe club hatchet - Is there a more definitive idea of what tribe it came from? Length 16"

Thanks for looking and hopefully unravelling any clues.
Cheers, David
