Problem:For codebreakers with the allied forces, it was more important a discovery than the Enigma machine, offering encryption for the Nazi command that, when cracked, would hasten the end of the second world war and lead to huge breakthroughs in modern computing. 
  
  
  
 Less than 80 years later, for a thrifty woman in Essex, the “telegram machine�? was little more than a dusty old gadget languishing in the garden shed. 
  
 But after an eagle-eyed volunteer with the National Museum of Computing (NMC) spotted an ad on eBay this week, the extremely rare, military-issue Lorenz teleprinter has been saved and provides the latest piece in international efforts to rebuild Hitler’s complete encoding device. 
  
 After finding the component on the online auction site, and receiving a long-term loan of the Lorenz SZ42 cipher machine from the Norwegian Armed Forces Museum in Oslo, the NMC is now looking for the final parts to restore the encoder to working order.

 “To do that we have to replace some missing components, in particular the drive motor – and it’s the drive motor that’s our next quest,�? said John Whetter, a volunteer engineer with the NMC. 
  
 Whetter and his colleagues are calling for people across the country to search their sheds and attics for the device, which looks like a small rugby ball with spindles poking out of either end. 
  
 It was just such a coincidence that led to the museum getting its hands on their Lorenz teleprinter, after they spotted it for sale. “I think it was described as a telegram machine, but we recognised it as a Lorenz teleprinter,�? Whetter said. 
  
 They rang the seller and drove to down to Essex to take a look for themselves. “The person took us down the garden to the shed and in the shed was the Lorenz teleprinter in its original carrying case,�? Whetter said. They snapped it up for £9.50. 
  
 But the true value of their purchase was yet to become clear. It was only after cleaning the machine at Bletchley Park, where the museum is based, that they found it was a genuine military issue teleprinter, complete with swastika detailing and even a special key for the runic Waffen-SS insignia. 
  
 Together with the cipher machine from Norway, the teleprinter almost completes the museum’s set of encryption, interception and decryption equipment, which will allow them to tell from beginning to end the tale of how the allies broke Germany’s secret codes. 
  
 Having heard the story of the teleprinter’s discovery on the BBC on Sunday, two former pupils of a school in Finchley, north London, have raised hopes of finding the drive motor. One said he would never forget seeing one on a cabinet in the the headmaster’s office while he was being caned. 
  
 Another said there had been a Lorenz machine in the head’s classroom. The NMC is chasing down the leads. 
  
 More complex than the famous Enigma code, the Lorenz cipher could be broken only thanks to the mathematician Bill Tutte, who deduced the architecture of a Lorenz machine without ever having seen one. 
  
 Solving the problem also led to the creation of Colossus, the world’s first programmable computer, which Tommy Flowers, a Post Office engineer, invented to work out the wheel positions on the Lorenz encryption machine and reduce the time taken to decrypt messages from weeks to hours. 
  
 The decoding of the top-secret Lorenz messages is credited with shortening the war and saving countless lives. “It was the highest possible level of security used by the German high command,�? Whetter said. 
  
 It was thanks to the breakthroughs by Tutte and Flowers that allied commanders could be certain Hitler’s high command had bought their bluff that the D-Day invasion force would be landing at Calais, rather than on the beaches of Normandy. 
  
 The museum is hoping to recreate the encryption and decryption process at a special event on Friday. ||||| Image copyright National Museum of Computing Image caption The teleprinter for the Lorenz cipher machine, which Hitler used to message his top generals 
  
 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. 
  
 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.

Solution:
You never know what you’ll find on eBay. Case in point: A volunteer with the UK’s National Museum of Computing spotted a rare machine used by the Nazis to send encrypted messages during WWII on the auction site, the Guardian reports. Listed as a “telegram machine,” the military-issue Lorenz teleprinter was being stored in a garden shed “with rubbish all over it” in Essex, museum volunteer John Wetter tells the BBC. The museum bought the machine for about $15. Initially, museum volunteers thought they had discovered a civilian version of the teleprinter. But later they realized it was a military-issue machine upon discovering a swastika and military serial number, according to the Telegraph. "Everybody knows about Enigma,” the museum’s Andy Clark tells the BBC, referring to the machine used by Nazis to send communications to frontline troops. “But the Lorenz machine was used for strategic communications.” The Lorenz also produced a more complex code than the Enigma, per the Guardian. But mathematician Bill Tutte was able to break it, leading to the creation of the first programmable computer, Colossus, that could translate messages sent via the Lorenz. “We were able to drip-feed the Russians the locations of the German tank divisions of Kursk,” Wetter tells the Telegraph, adding that it was the “turning point of the war.” On June 3, the National Museum of Computing plans to recreate the breaking of the Lorenz cipher code using the teleprinter and a Lorenz cipher unit on loan from Norway’s Armed Forces Museum. But there is still one more missing component: the electric motor, which the museum is asking the public to keep an eye out for. (This man believes a $500 million treasure is hidden in a Nazi bunker.)
