ATM. England. 1950
The Government Communications ATM device was made to order in England. The phone belonged to the Head of the Department of Internal Communications of Soviet troops. This model was fairly widespread in the Government of the USSR. In particular, it is similar to the model used by Nikita Khrushchev to speak with astronauts Andrian Grigoryevich Nikolayev and Pavel Romanovich Popovich on August 15, 1962, a few hours after their landing.
The Museum in Moscow also has an interesting mounted device in a British Telephone Box, similar to the one that belonged to Winston Churchill.
In 1941, during the Battle of the Atlantic, Churchill was in a bunker in Liverpool, where the government hid. The bunker was equipped with a secret phone box with its own hot line. This command bunker played a key role in the Battle of the Atlantic.
