Sword from Angola. Chokwe, Salampasu?

[Pieje]

I didn't read the whole topic, but it's a very nice southern Congo sword (Angolan border). Imo late 19th C, but could be very early 20th C.
Attached one I had in my collection once.
Mostly these are attributed to the Tchokwe or Lunda (or Kaniok).
This type is much less common than the classic Yaka swords.

Pommel may be original, they do exist with and without cone.
I attached 2 classic Yaka swords with damaged pommel (don't have better pics). When an original cone is removed, it's ugly, not like the sword of the OP.
