I believed we hold this individual's Mauser rifle. Carved 'J. G. W. Basson, Gaberones South Africa, June 3rd 1900' on the butt, the serial number is B1810 and was donated in 1901. I'm presuming this is also the individual that was captured 1901/07/28 and sent to Bermuda!
If you contact Audrey in SA (details in Contacts on the menu bar), she will be able to copy the form used to apply for this medal. There would be a cost for doing this however and Audrey will be able to tell you what this would be.
