Mooch also found one of the German WW2 naval four-rotor Enigma machines.
(23-Sep-2008)
There is a big collection of WW2 wireless equipment, some of these were used to listen to the German messages.
To decipher the Enigma messages was very difficult and Alan Turing developed a machine called a Bombe to help.
In 2007 a fully working Bombe was unveiled by the
Bombe Rebuild Project
Over 200 Bombes were originally built , but all were destroyed by the government after the war.
Mooch was allowed to switch on the Bombe by one of the rebuild team.
