This is a general report on the origin, development and status of the Hagelin "cryptographers"--a word used here to describe the physical machines (rather than the people working on codes). After his father invested in Aktiebolget Cryptograph, Boris C.W. Hagelin (1892-1983) took over ht leadership of the company in 1925, producing several fine models of encoding crypto machines, using Arthur Scherbius' (as in the "Scherbius Principle", 1878-1929) rotor designs, some of which were marketed under the name "Enigma" (models of which were purchaed by the Wehrmacht in 1926 and modified for heavy use in the '30's and through WWII). The company produced 140,000 units during WWII (while headquartered in the U.S) and is still in business today as Crypto AG, in Zug, Switzerland.

Sections in the document 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 a final section "How to Sell Cryptographers". There is a mention of the "Enigma" machine on page 14, which is limited to mentioning that it is not sold outside of Germany. Although the Swiss firm founded by Boris Hagelin has manufactured, and continues to manufacture, many kinds of cipher machines, the words "Hagelin machine" will normally inspire thoughts of their unique lug and pin based machines.
