I had this in my section of items I bought while stationed in the H.O.A. with the US Navy CB's. I was not sure when I bought it back in 2010 but thought it was French, since they are so many of them in that area.
But recently someone informed me that this was from Mad Mike Hoare's 5 Commando that operated in the Congo in the 1960's. I was hoping some of many British or South African collectors might have some thoughts on it?
The black one is the Djiboutian national police force. I got it from my translators father who retired in 2009.
