Schlüsselgerät 41 (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 wohl für den deutschen Wetterdienst vorgesehen und verfügen 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 Restaurierung des sehr seltenen und mechanisch äußerst komplizierten SG 41 wurde von einem Experten mit hohem Aufwand im Verlaufe eines Jahres umgesetzt. Dabei wurde die Maschine komplett zerlegt, gereinigt, entrostet, brüniert und konserviert. Nicht mehr brauchbare Originalteile (Codierscheiben/Schlüsselräder) wurden nach Originalvorlagen 1:1 nachgefertigt. Nach Einliefererangaben lässt sich die Maschine mechanisch bedienen, Rotoren und Codierscheiben werden angetrieben. Vollständigkeit und Funktion der Chiffrierung konnten von uns nicht überprüft werden. Abmessungen 27 x 31 x 17 cm, Gewicht ca. 10 kg.

A cipher machine 41 (SG-41), known as the "Hitler mill", made by the Wanderer-Werke in Chemnitz
The "Z" version of the SG 41 cipher machine was referred to as a weather machine. Since the main user was the German weather service, they were only fitted with a numerical keypad.
Based on the encryption principles of the Hagelin machines the SG 41 featured several significant improvements, that made it unbreakable using the decryption technology of the time. Not many machines were deployed as of 1944 owing to disputes about matters of competence and production problems.
The time-consuming restoration of the extremely complex mechanism of the SG 41 took a noted expert over a year. To this end, the machine was completely dismantled, cleaned, the rust removed and all parts coated with protective bluing. Parts beyond repair (the rotors) were replaced by custom-made components. According to the consignor, the machine is mechanically operational, the rotors and code disks in working order. However, we have no means of checking proper encryption and completeness of the machine and sell it as is. Dimensions 27 x 31 x 17 cm, weight approx. 10 kg.
