Vulcan XL388 was deliverd to the RAF in June 1962. To be used in 'Goldfinger' it's cockpit would have to have been filled with water when it was three years old. After all that it would have ben eventualkly flown to Honington in April 1982 so the RAF Regiment could set fire to it. It could well have done the flyimg bit in the film.
I got the year wrong. It was in late 1964 that I can remember XD 814 sitting there, minus a cockpit. That was on a civilian truck; destination Pinewood studios. Thunderball was made in 1965.
