National Museum of Military History

The National Museum of Military History, Diekirch, Luxembourg, exhibits a 1941 3-rotor Heer Enigma and a US M-209 converter. They also have a large collection of other communications equipment. Although it is a small museum, it is loaded with a huge amount of material in the center of Diekirch.

The Enigma and M-209 were acquired as a long-term loan from the National Cryptologic Museum on 28 August 2004 and, since 30 September 2004, have been integrated into the museum's communications equipment exhibit.
