The P-51 was briefly owned by Mike Keegan (Of Trans Meridian/British Air Ferries fame / and he was also the K in BKS). He had it repainted at Luton if I remember correctly.? I recollect meeting a guy who was involved in the painting.
It was I think also involved in an accident at one of the Biggin Hill air shows when a parachutist landed nearby and got entangled in the moving prop-not sure of the outcome now-as the memory is fading fast!
