An important Cold War spy radio supplied to British Agents and Special Forces, such as the SAS and SBS. The Mark 301 was designed by S G Hart when working for HMGCC at Borehamwood in the UK. It was a lightweight portable alternative for the wartime MCR-1 (biscuit tin radio used by SOE and OSS agents), and was built around 5 subminiature valves. The radio operates on a wide band of frequencies from 500kHz to 18.5Mkz, divided into 4 ranges and hence the four positions for the coil pack. It is powered by a battery pack or from the mains, and had an external aerial wire and an earphone, in this example these are not present. It is said that only 800 examples of the Mark 301 radio were made.
