Here's an example in my collection awarded to 5219 Sjt. T.F. Bridges, 2/West Yorkshire Regt.
The group is interesting for reasons other than the single clasp KSA too. The QSA is named to Pte. T. Frost who (as verified in research documents) changed his name from Thomas Frost to Thomas Frost Bridges between qualifying for his QSA and his KSA. He was wounded at Willow Grange 23/11/1899 and invalided. He returned to South Africa in 1902 and it's clear that his period of convalescence in the UK counted towards the qualifying period of 18 months for his KSA.
He re-enlisted in the West Yorks in WW1, serving in the 1st, 4th and 9th battalions. He was wounded in the face at Gallipoli and was invalided home for a while suffering from rheumatism. In 1917 he was appointed Acting RSM and then commissioned following a glowing reference from his CO. Quite a biography for a humble steel labourer from Sheffield!
