There was a Gannet in the 705Sqn hangar at Culdrose in 83 just a year after the Falklands conflict. It was being used for noise research (by Dowty??) as there was talk at the time of using unducted contra-rotating fans on commercial aircraft. It flew several times.
That would be XL500. It went to Chatham Dockyard after that, until being bought by Kennet Aviation. It is now at Exeter Airport under restoration to flying condition again.
