The HELL STG-61 1 was a small hand-held cipher machine, built in the around 1961 by Rudolf HELL in Kiel for the post-war German Border Police as a replacement for the refurbished Enigma machines that were used until then. The STG-61 is one of two mechanical cipher machines, the other one being the H-54, that were built by HELL under license of the Hagelin Company in Switzerland. It is a purely mechanical machine, that can easily be hidden in the pocket of, say, a coat.
