BID/60, also called Singlet,^[1] was a British encryption machine. It was used by the British intelligence services from around 1949 or 1950 onwards. The system is a rotor machine, and would appear to have used 10 rotors. There are some apparent similarities between this machine and the US / NATO KL-7 device.
