JEM60
The Hunter that you saw in SA would be XE653, which Keith Hartley delivered from Exeter to Cape Town in the mid nineties.
It was an original 111 Squadron machine; after a long career at Chivenor and Brawdy it was retired to Scampton as a GI airframe. While at Scampton it was repainted gloss black, and it was still in those colours when it was sold to Thunder City. I believe that it was resprayed yellow for a TV advertising campaign.
