Swiss Model 45 NEMA cipher machine.
Type T-D (Tasten-Druecker-Maschine) enciphering machine, serial number TD 521, Switzerland, manufactured by Zellweger AG, c.1950. The machine with ten wheels, four of which are coding wheels, one a reflector (right side red wheel, similar to the enigma construction), and the other 5 all driving wheels, mounted under hinged cover is letter counter, lamp panel and standard keyboard layout, 4v electrical input to the side and mains lead inside, the inside lid of the cover with external lamp panel, lamp cable, 14 spare bulbs, 2 extra wheel cases, each containing a pair of wheels, and a contact cleaning brush. The carrying case lid with stencilled numbers 521 and TD521, and special printed red and white period label indicating its use in time of war, leather carrying handle, lock and key present. The carrying case 14 1/2 x 12 3/4 x 5 1/2 in (36.5 x 32.5 x 14 cm).
WITH: Original NEMA instruction booklet, in German and French, marked SECRET, and stamped 785, with declassification stamp at center of front cover dated February 13, 1998.
A FINE AND RARE SWISS NEMA MACHINE, 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, as this example, put aside in bunkers around Switzerland in preparation for the next world war. These Kriegsmobilmachungs-Maschine or K-Mob-Maschine all have the white label printed in red on the case which reads: "Nur bei Kriegsmobilmachung abgeben ! / Ne délivrer qu'en cas de mobilisation de guerre ! / Da consegn. solo in caso di mobilitazione di guerra !" They were generally unused except for occasional testing, and appear to be released only very occasionally.
