Head of Department
The NEMA utilised a total of 10 rotors: 5 for enciphering the alphabet, and 5 paired rotors which give irregular stepping of the rotors. This was a marked improvement over the original German counterpart, Enigma.
The high serial number denotes that the present machine was produced as an Operational Machine for wartime use only, rather than a Training model or a scarce Foreign Office version.
The present Lot includes a bilingual operations manual stamped ENTKLASSIFIZIERT DATUM: 9 Juli 1992, which denotes the official declassification date for the NEMA.
Please note that the cataloguing date should read 'third quarter of the 20th century'.
