Secret WW2 Lorenz teleprinter code machine found on eBay...

Secret WW2 code machine found on eBay
Sun, 29 May 2016 - After a secret German WW2 code machine is found on eBay, the National Museum of Computing is asking people to search for its motor.

A historic machine used to swap top secret messages between Hitler and his generals has been found languishing in a shed in Essex. Volunteers from The National Museum of Computing at Bletchley Park used eBay to track down the keyboard of the Lorenz machine. It was advertised as a telegram machine and was for sale for £9.50.

A Lorenz teleprinter

The museum, in Buckinghamshire, is now asking people to search for the motor, another key piece of the equipment. "My colleague was scanning eBay and he saw a photograph of what seemed to be the teleprinter," said John Wetter, a volunteer at the museum. He then went to Southend to investigate further where he found the keyboard being kept, in its original case, on the floor of a shed "with rubbish all over it". "We said 'Thank you very much, how much was it again?' She said '£9.50', so we said 'Here's a £10 note - keep the change!'" The teleprinter, which resembles a typewriter, would have been used to enter plain messages in German. These were then encrypted by a linked cipher machine, using 12 individual wheels with multiple settings on each, to make up the code.

'Bigger than Enigma'

Andy Clark, chairman of the trustees at The National Museum of Computing, said the Lorenz was stationed in secure locations as "it was far bigger than the famous portable Enigma machine". "Everybody knows about Enigma, but the Lorenz machine was used for strategic communications," said Clark. "It is so much more complicated than the Enigma machine and, after the war, machines of the same style remained in use." The museum has just received one on loan from Norway's Armed Forces Museum, and has a video of how top secret transmissions might have sounded. Volunteers are hoping to recreate the whole process on Friday 3 June, from typing a message in German to cracking the code using wartime equipment. "This gives us the chance to show the breaking of the Lorenz cipher code from start to finish," said Andy Clark. "We can show every single point in the process."

When volunteers took the teleprinter back from Essex to the museum, they found it was stamped with the official wartime number from the German army that matches the one on the machine from Norway. But one key part is still missing and volunteers are still searching for it. "It looks like an electric motor in black casing with two shafts on each side, which drive the gears of the Lorenz machine," explains volunteer John Wetter. Volunteers hope the public will look out for it and if all else fails are hoping someone might want to build them a new one until they find it.

I'm currently reading Max Hasting's new book on Britain's secret war against Nazi Germany. I have read a couple of books on the subject, including a biography of Alan Turing, the brilliant mathematician codebreaker at Bletchley Park during the Second World War. American codebreakers also played a major role in the Battle of Midway, who correctly deciphered Japanese messages, and AF was thus confirmed as Midway. Yamamoto Isoroku was planning another surprise attack but the Americans knew his secret plan to attack American fleets at Midway in advance.
