The BC38 pictured here was used as a 'back at base' machine and could decipher and encipher C38 messages. It had a keyboard and an electric motor and was intended for use in clean and dry conditions so did not see front line action.
The C35 and C36 (pictured) were cipher machines designed by the Ukranian cryptographer Boris Hagelin for the Swedes in the 1930s. These were the first of Hagelin's machines to feature the pin and lug mechanism later used by many makers. The French had asked for a machine small enough to fit into an army great coat pocket and this was the result. These early 'portable' machines were thought to have weak encryption and were rejected by the US Army, although the French still bought 5,000.
Above is a remarkable fully working replica of an Enigma machine built completely from scratch by enthusiast Ken Hutchins. All of the major components are made from clear acrylic allowing the inner workings of the device to be seen in action.
