I'm not going to annotate all the pics with their reggies as all the red and white Hawks of 4FTS were registered XX--- with the 3 number code on the nose and tail completing the reg.
The TWU Hawks followed a similar line with their aircraft initially, but at some point possibly in 1979, the TWU at Chivenor adopted their own system of tail codes and there are aircraft with the same reg but with different tail codes from the TWU in this set.
