Lot 2397 | Schlüsselgerät 41 Z (SG 41), sog "Hitlermühle" der Wanderer-Werke in Chemnitz
Schlüsselgerät 41 Z (SG 41), sog "Hitlermühle" der Wanderer-Werke in Chemnitz
Bei der "Z"-Version des Schlüsselgerätes SG 41 handelt es sich um eine sog. Wettermaschine. Diese waren für die geheimen Wetterstationen der Wehrmacht z.Bsp. auf Grönland oder in der Arktis vorgesehen und verfügten lediglich über eine Zifferntastatur. Das Konstruktionsprinzip der SG 41 basiert auf dem der Hagelin-Maschinen, enthält aber eine Reihe wesentlicher Verbesserungen. Mit den damaligen Mitteln der Entschlüsselungstechnik war diese Maschine unknackbar. Aufgrund von Kompetenzstreitigkeiten und Fertigungsproblemen kamen aber nur sehr wenige Geräte ab 1944 zum Einsatz. Die Kurbel ist unterseitig mit "9." punziert, es dürfte sich also um eine der ersten Maschinen handeln.
Das Gehäuse wurde nachlackiert, die Beschriftung erneuert und die lose beiliegende Grundplatte durch eine moderne ersetzt. Die innenliegende Mechanik wurde nicht zerlegt, lediglich schonend gereinigt und konserviert, um die Reste des Finishs zu erhalten. Die kleinen Plexiglasscheiben sind die werksseitig eingebauten Originale und wurden wieder befestigt. Nicht funktionsfähig, da die Kunststoffmasse der Walzen durch Feuchtigkeitseintritt zersetzt wurde, was ein "Durchkurbeln" der Maschine verhindert. Dazu die Reste des originalen Reinigungspinsels und der Drahtbürste, zwei Holzrollen sowie eine moderne Farbkopie der Wartungsanleitung, Abmessungen 27 x 30 x 17 cm, Gewicht ca. 10 kg.
Sehr seltene Schlüsselmaschine.

A cipher machine 41 Z (SG 41), known as the "Hitler mill", made by Wanderer-Werke in Chemnitz
The "Z" version of the SG 41 cipher machine was referred to as a weather machine. They were intended for use at the secret Wehrmacht weather stations, such as that on Greenland or in the Arctic, and were only fitted with a numerical keypad. Although the principle of the SG 41 is based on that of the Hagelin machines, it includes a number of significant improvements. This machine was unbreakable using the decryption technology of the time. Very few machines were deployed after 1944 owing to disputes about matters of competence and production problems. The crank is marked "9." on the underside, meaning it is probably one of the first machines.
The housing has been re-lacquered, the lettering renewed and the loose base plate, also enclosed, replaced by a modern one. The interior mechanism was not disassembled, only carefully cleaned and preserved to protect the remainder of the finish. The small Perspex panels are the factory-fitted originals and have been re-attached. Not functional because the plastic material of the rotors has disintegrated due to moisture ingress, which prevents the machine from being properly cranked. Also includes the remainder of the original cleaning brush and wire brush, two wooden rollers as well as a modern coloured photocopy of the maintenance manual. Dimensions 27 x 30 x 17 cm, weight approx. 10 kg.
Extremely rare cipher machine.
