Hi Jim,
Thanks for you fast reply.
Here I have some more pictures of the copper inlay, there are on bouth sides.
The iron on the handle is, I think painted in gold collor.
We will see later on other reactions.
May this is more intresting, this was also one of the knifes I found yesterday

The last picture, its also in the new book of Jan Elsen, its a Ngbandi knife
Kind regards
Jos
