South Africa Medal 1877/89 clasp 1877-8 named CAPT J WILSON BOLOTWA VOL. Very fine and rare to a unit C.O.
A little-known unit of Europeans, the Bolotwa Volunteers - under the command of Captain Wilson - were awarded 18 Medals, all of them with the '1878' clasp, 5 of these being returned to the Mint.
Presumably Wilson had seen further service in the 1877 campaign which qualified him for the '1877-8' clasp. As stated the Volunteers roll suggests just the '1878' clasp.
