'Biscuit Tin' radio, British Government Miniature Communications Receiver, Mark 1 (MCR1), 1943. Box containing two receivers, two PSU and two extra tuning coil units.

During World War II, these compact radios were dropped by a parachute hidden inside the biscuit tins. They were crucial to resistance fighters in Europe because the Germans had confiscated all normal civilian radios. BBC London's public broadcasts were used to communicate with resistance groups by using obscure "personal messages" which had secret meanings.
The receiver was developed in 1943, and by 1945, 30,000 of them had been made. After the war, they became a collector’s item due to their rarity.
