On eBay: German WWII Enigma Cypher Machine
By James Grahame
There's a museum quality Enigma cypher machine on eBay with a "buy it now" price of $100,000.
The German military used the infamous Enigma cypher machine to encode some of their communication during WWII. The machine triggered a game of cat and mouse, as a team of British code breakers and Polish mathematicians at Bletchley Park rushed to crack the code. They kept their breakthrough an absolute secret for decades, perhaps because the USSR used similar technology during the early part of the cold war.
If $100K is a tad over your Visa limit, check out the modern Enigma-E electronic version, available from the Bletchley Park shop for £119.99 + postage.
