The Scheuble apparatus
During World War 1, on the front between the Austro-Hungarian Empire and the Kingdom of Italy, weak codes and ciphers and their usage greatly aided Austrian intelligence in breaking the most secret Italian messages. As an aid some ingenious mechanical devices were constructed which assisted the Austrian codebreakers in their work. Few rare and precious exemplars still exist in a museum and those are described and analyzed and shown in various figures within this article.
