Looking at the Remark vehicles, I think the Dorbyl/Sandock Austral entry was the one second from left, alongside the Buffel.
The description given by that chap that I posted earlier stated that the competition was structured so that the winning vehicle would be further developed, incorporating ideas and features from the other 3 losing vehicles that were desirable.
So the Veldskoen was a further development, but the vehicle you posted is the Sandock Austral Ingwe.
If you look at the Dorbyl/Sandock Austral entry, they share features.
It looks like the Ingwe is a simpler development of their original entrant into the Remark competition. For example, the commanders cupola is no longer present, which also entails a change to the hull shape in that area, as well as changes to the front of the vehicle.
Perhaps when they developed the line on and as it morphed into a new vehicle (Veldskoen) they simply took their original prototype and reorientated the design into a simpler vehicle and role?
Same company, same axles, looks similar to their original Remark entry.
Again, this is pure speculation on my side.
