Colossus Machine Fragment
Colossus, named for its extraordinary size, was designed by Tommy Flowers from the GPO Research Station at Dollis Hill to process German Lorenz (Tunny) messages. The first working model of Colossus arrived at Bletchley Park in 1944.
Colossus was the first large-scale electronic digital computer and only a few original Colossus fragments survive.

Abwehr Enigma G - serial no. G312
This model G is smaller than most German military Enigma machine. Like the early commercial models of Enigma, this machine does not had a plugboard on the front. Unusually, the Enigma G’s small rotors are controlled by gears, which move them in an irregular pattern.
This type of machine was used by the German Military Intelligence (Abwehr). Due to the lack of plugboard, the ciphers created by these machines were less complex than those produced by later models. They were therefore more vulnerable to the analogue decryption methods developed by GC&CS during the 1930s

Lorenz T-32 Springschreiber
A 1930s teleprinter manufactured by the German Lorenz Electronics and Electrical Company. A teleprinter is an electromechanical typewriter used to send and receive typed information in the form of teleprinter code. The Lorenz cipher attachment (Tunny) was an ‘in-line’ machine that was attached to a standard teleprinter such as the Lorenz T-32. Messages were typed by the sender in plain text on his teleprinter and appeared again as plain text on the receivers teleprinter. The sender and receiver would not normally see the cipher text produced by the cipher attachment.

Hut 8
It was in Hut 8 that the Codebreakers managed to break the top secret German naval Enigma ciphers. Their work provided crucial day-to-day intelligence during the Battle of the Atlantic. It allowed the Admiralty to re-route Allied convoys bringing vital supplies to Britain around the enemy U-Boats hunting them down. The team here was led by mathematician Alan Turing and chess champion Hugh Alexander.
John loves his job. It's beyond me why, since all he does is having these super-intense phone conversations, clicking strange lines of code on his laptop and reading about things like Java spiders, bots and aggregators (!), but still he loves it. I captured him working on something from home the other morning - the light was scarce but very pretty.

Alan Turing’s office
Here at his desk in Hut 8, Turing took the lead on breaking naval Enigma ciphers - something few thought could ever be done. His mathematical skills also enabled him to break other ciphers, including the complex Lorenz cipher where he used a method that became known as Turingery. Together with he’s fellow Codebreaker Gordon Welchjman, he developed the Bombe machine to help speed up the codebreaking process.

Lorenz Schlusselzusatz SZ42 Ciper Attachment
Manufactured by the Lorenz Electronics and Electrical Company, these cipher machines were used for message passed between German Army Field Marshals and Generals at the front lines and their High Command in Germany. Enciphered messages (traffic) enciphered by this machine were given the codename Tunny by Bletchley Park.
This machine was captured from Field Marshal Kesselring’s communications vehicles by the Allies in 1945 and brought to Beaconsfield in the UK for investigation and operational testing.
