The rebuilt Bombe, the machines used to crack the Enigma code:
The sadly neglected huts that the code breakers worked in:
A Harrier Jump Jet, which had no discernible reason for being here:
The rebuilt Colossus computer (another code breaker, and the first digital computer):
The office of Alan Turing during the war:
The full set will be up in a week or two. More on Saturday.
