I bought this medal grouping a few years ago from the mans daughter and her sister(they live in San Diego now). He was with the South West Transvaal Rifles during the Great War and according to the daughter was the sole survivor of the Regiment.
He later served in WWII as well and has the medal for that as well. The medal bar was put together by his wife which is why it isn't quite up to standard. The diary is very cool as he describes his units search for German troops in the Veldt.
