This one could only be the Spanish Austin Victoria (built by Authi) as it is a top-of-the-range model with twin round headlamps.
No South African-built Austin Apache was offered with twin headlamps, as they all had single rectangular lights, irrespective of trim level, whereas only base Spanish Victorias used the rectangular lamps. I hope this helps.
I have a feeling this car is a repost and can now be merged (I think Carnut posted it some time back), but the search function doesn't seem to be working at the moment so can't find the original puzzle.
