[jaxonrice]

I now suspect that this is a form that genuinely appears on two continents in slightly different guises, as I have seen quite a few of similar shape and form in Southern Africa.

Whilst not of exactly the same form, here is another similar example. The attached picture in this post is of a club that appeared at an auction house in Cape Town in 2013, attributed as a 19th century Zulu knobkerrie.

The example from my previous post which sits at the Royal Museum for Central Africa, was purchased from the National Gallery of Zimbabwe. I highly doubt it originated in the Rennel Islands.

The circumpunct, or circle with a point at its centre, is also not a help with identification as it appears in so many diverse tribal cultures.
