Pin made in Soviet Russia. The pin shows the Tupolev ANT-44. The text on the pin reads:”Naval heavy amphibious bomber″, “Six world records” and “Participant of the Great Patriotic War”.
The Tupolev MTB-2, also known as the ANT-44, was a Soviet four-engine flying boat built in the late 1930s.
The first prototype crashed during flight testing and the second aircraft set a series of world records by a flying boat later that year. After the Axis invasion of the Soviet Union in June 1941, it flew bombing missions against targets in Romania and then along the Black Sea littoral as Axis troops advanced deeper into the Soviet Union. In 1942 the aircraft began evacuating wounded troops and also resumed its previous role of strategic bombing Romanian targets until its loss later that year.
