Something of a digression, a conversation about a person who may still be living at Doncaster, close on 100 if he is, but I saw him 2 years ago, and he looked much the same as ever! A colleague described him as being very highly skilled having built Lancaster bombers in the war. I knew this to be untrue and was able to correct it thus. "He was even more highly skilled than you think, his craft was toolmaker, so he made the tools which were used to build the Lancasters!
