London: An encoding machine used by Nazis during the Second World War to encrypt messages will be auctioned later this month.
The three-rotor Enigma machine is expected to fetch thousands of pounds when auctioned at Christie`s on September 29, the Daily Mail reports.
The Enigma, which was originally produced by a Dutch company for commercial use after the First World War, was considered the most advanced machine of it`s kind and paved the way for modern computer systems.
The machine was capable of encoding messages before sending them via Morse code to another machine, by using its complicated system of rotors.
Christie`s specialist James Hyslop said that the technology was bought for sole use by the German military in 1929 who believed that the code used by the machines were impossible to crack.
However, a team of cryptologists, linguists, scientists and data analysts at Bletchley led by the English mathematician Alan Turin were able to crack its code.
In November last year, the world record price for one such machine sold at an auction was set at 67,250 pounds, and this machine is expected to top the amount.
