He was definitely in the Boshof area, two of his witnesses list Merriesfontein (just outside Boshof) and the 3rd lists his address as P.K Boshof, I.e. Post Office Boshof. Looking at his writing it could be Continel or similar, his n and u being close., sorry no closer to getting the actual name, but Knapdaar is NW of Boshof, so at least you are in the right area.

P.K. Content Stasie

There is a farm called Content in the area, could possibly be a railway siding or store there that doubled up as a post station
