Never seen a green cockpit inside. Mines was 1951, cockpit interior all black.
Unless in some distant past it had a full interior refurb, which I doubt, it has always been black.
RAF Turnhouse, and St Andrews, was where it lived for most of its life.
I also have some fifties, and sixties external photographs of mine, in various guises, and interior looks black.
Maybe some one off's were green inside.
