Pin made in Soviet Russia. The pin shows the Tupolev SB also known as Tupolev ANT-40. The text on the pin reads:”High-speed bomber, cantilever mid-wing aircraft”, and:”Two world records for altitude with cargo”, and:”Participant of the Great Patriotic War”.
The Tupolev ANT-40, also known by its service name Tupolev SB, was a high speed twin-engined three-seat monoplane bomber, first flown in 1934.
Numerically the most important bomber in the world in the late 1930s, the SB was the first modern stressed skin aircraft produced in quantity in the Soviet Union and probably the most formidable bomber of the mid-1930s. Many versions saw extensive action in Spain, the Republic of China, Mongolia, Finland and at the beginning of World War II against Germany in 1941.
