Pin made in Soviet Russia. The pin shows the Tupolev ANT-3. The text on the pin reads:”The first serial all-metal aircraft”, and:”22000 km. 1927 Flight Moscow-Tokyo-Moscow″.
The ANT-3 was a Soviet all-metal aircraft designed by the Tupolev Design Bureau. Tupolev acquired much experience in building his first two aircraft, later using his experience to construct the ANT-3. By this time, Soviet Air Force leaders were convinced that metal was a highly usable substance in the building of airplanes. The ANT-3 was Tupolev’s first practical aircraft.
