The Bombe Breakthrough, technical illustrations

Working closely with the author of the book, Dermot Turing, these illustrations were produced to explain complex code breaking processes and machinery, used at Bletchley Park during WW2. They were published in a guide to go with an exhibition 'The Bombe Breakthough'. https://dermotturing.com/my-recent-books/the-bombe-breakthrough/ The book is available from the Bletchley Park Shop.
