What I have determined is that the rolls are missing. The paper copies cannot be found. There was apparently a microfiche copy in the Transvaal Museum (as it was called then) but the museum does not focus on anything it considers colonial, and they don't know where it is.
The intention was to try to determine if there were any natives listed but did not get the medal, but this can't be done now unfortunately.
In my opinion many of the medals to natives did not reach the intended recipients. The ones in my collection are all in perfect condition and as such were probably not issued. They did, however, later make it onto the collector's market.
