Don’t know if you may have seen BBC Bombers first broadcast in 1980, original film by Ilef cousins of Lancs at Scampton. Also the Memphis bell documentary at the same time. I have these on VHS But cannot find it on the net.

There is reference to cork screwing in the Lanc footage. I could transfer this to disc, only thing is its been played that many times its a bit worn now, like me.:)

Second post attempt.
