A FINE AND RARE SWISS NEMA MACHINE, ALMOST MINT AND PREVIOUSLY IN MILITARY STORAGE, an example of the new breed of ciphering machines which developed from the German Enigma wartime series, in this case developed by the Swiss. Following the realization that their Enigma K series was compromised by the codebreakers of most of Europe, a team of professors from Bern and other universities, from 1941, began to develop this new machine, a prototype of which was made in 1944, and a design for manufacture which was passed in spring of 1945. The name NEMA derives from NEu MAschine, made by Zellweger AG in Uster. 640 machines (numbered 100-740) were built, the first was in active service by 1947, and many of the higher numbered machines (such as this one), have the special label pasted onto lid, and were put in storage to be used in time of war. NEMA was declassified in July 1992, and examples now come to the market on occasion. The NEMA machines were distributed as follows, those numbered under 100 were for training use and are mostly worn out, those allocated to the diplomatic service of which apparently none of which have been released, and those put aside for the next World War in bunkers around Switzerland, all of which have the red label on the case, they were generally unused except for occasional testing, and appear to be released only very occasionally.
