InformationWeek posts this article by Gregg Keizer of TechWeb that an Enigma machine from World War II is currently $30,000 on eBay:
eBay bidders have offered more than $30,000 for a World War II-era German Enigma cipher machine, a sum that’s “on the high side,” according to a dealer who has sold other models.
The online auction, which is scheduled to close Monday, is for a three-rotor Enigma machine manufactured in 1941, said the eBay listing. The unit, however, is missing a serial number, and the rotors — which typically are stamped with the same serial number as the Enigma itself — appear blank.
“Serial numbers has [sic] been removed,” the listing states.
