I can confirm the aircraft was at Thruxton on 16 Sept 1962 < I have it in a log I made>. That day was Thruxton Air Races so I cannot be sure if the the aircrfat was a visitor or resident. I also have a photograph of it at Wilson A/P Nairobi pre July 1957.
Also saw G-ADTD at Thruxton the same day, both a/c now sadly long destroyed.
