Machine Room

In 1941 this was where men and women actually breaking the ciphers worked, using just pencils and paper. It took intense concentration to calculate which rotors were being used, the order they were put in the Enigma machine and the settings. They were sometimes helped by a ‘Cilli’ - the careless use of a predictable name or rude word by an Enigma operator.

1947 Sunbeam Talbot

2 litre Sports Saloon converted to a Tourer

Shipped to Simpsons of Madras when new on 12th September 1947, this car was oringally light green, which is still visible in some places. Following its return to the UK the car was generously donated to Bletchley Park Trust by Mick Jagger after starring in the film Enigma (2001) which was produced by Jagger’s film company.

Loosely based on real events, the film follows the story of cryptanalysts at Bletchley Park facing their worst nightmare: Nazi U-boats have unexpectedly changed their Enigma cipher and a merchant shipping convoy with 10,000 people on board is in peril.

Jagger required a period sports car for the starring role, which had a large enough boot into which a secret compartment could be built to house the Enigma machine. A Sunbeam Talbot 2 Litre Tourer would have been ideal, but they were rare in 2001, therefore this Saloon was acquired. The while of the body from the scuttle backwards had been removed and replaced by a custom 4 seater Tourer body and windscreen with the required compartment behind the rear seats. Notice the blackout headlights.

Netz Room

To test out possible settings for the day’s Enigma keys, large pieces of paper, known as Netz sheets, were punched through with holes according to the keys sent in various messages. The sheets were then stacked over a light. If the light shone up one hole through the whole stack it was called a ‘drop’ indicating settings that might be correct.

This is one of the largest rooms in the Mansion. Temporarily adopted as an office by the Military Section in 1939, the Dining Room was mostly used during the war as a place for eating and recreation.

In the late 1930s, there were a few hundred staff at Bletchley Park, and meals were served to them by waitresses. In 1938, a top London chef from the Savoy was even temporarily brought in by management to cook for those early codebreakers.

In 1942, the operation at Bletchley Park had grown much bigger and different catering arrangements were established. The large new canteen opened on Wilton Avenue, and this space, whilst still used as a dining room, was sometimes handed over to the Recreation Club for lectures.

The Leon family, who owned Bletchley Park pre-war, were responsible for the design and construction of this splendid room. Much of it’s Edwardian grandeur remains, despite the thousands of people who have worked - and eaten - in here since

Polish Bomba

(scale replica)

The Bomba machine was developed by the Poles to help find individual Enigma keys. The rotors you can see on top mimic the rotors of an Enigma machine.

The machine cycled through possible Enigma rotor positions. It looked for patterns that allowed the starting rotor settings for a particular message to be identified.

Set of Enigma I rotors

On 15th December 1938 the Germans started to use more rotors with Enigma. Three rotors could now be chosen from a range of five and inserted into the machine in any order.

The possible options for Enigma rotor order increased from six to 60. this made encryption even more secure, and messages harder to decipher.
