1968 WB627 silver airframe and thick sticky black plastic dayglow. There were rolls of it on the flight for minor
repairs and silhouettes of Chipmunks etc, for staffers cars.
21st June 1975 WG458. The colour scheme had changed to red, white and grey; the flying suits had changed from
blue to green and the bone domes had changed from silver (Mk 1c?) to white (Mk 2A).
Between the two schemes, the silver and dayglow changed to grey and dayglow stipes. I believe that originally as
delivered from the factory, they were silver airframes with yellow bands around the fuselage as noted above.
