This is a general report on the origin, development and status of the Hagelin “cryptographers”-a word used here to describe the physical machines used in encoding messages (rather than the people working on codes). It is an internal and “confidential”  report, slender and to the point. Its sections include “Models Built at Express Demand of the French Authorities”, “Evolution of Hand Cryptographer Type C-362”, “Hagelin Cryptographer Models” (BC-38 and C-362), “Methods of Operation”, “Superiority of Hagelin Cryptographers over Competing Makes”, and others, including “How to Sell Cryptographers”. Of particular interest to this post is the mention on page 14 of the “Enigma”, which is really just a very lonely statement, limited to mentioning that the machine is not sold outside of Germany. Of course we well know that the Enigma (which is one of a family of related electro-mechanical rotor cipher machines) was being used very heavily inside of Germany–and France, and the Soviet Union, and several other countries, though it was in fact being used by the Nazi military. It just feels odd and uncomfortable to see this ordinary commercial mention of the machine whose working and transmission was known to the Allies, a knowledge that may well have been one of the great turning elements of the war. And there it is, on page 14, in a restrictive distribution announcement.
