BT-7 Russian light tank, model 1937, early version
Eastern Express 35111

Production of the BT-7 Russian light tank with a conical turret began in 1937. Main armament remained the same, but the ammunition was increased by 44 rounds. All serving tanks now installed the DT machine gun in the rear niche. For the firing of the gun and coaxial machine gun at night, the tank was equipped with two special projector-type headlamps, and a mask placed on the gun. Subsequently, these lights were retrofitted to earlier models of the tank. Improvements were also made to the drive wheels, caterpillar tracks and gearbox by 1938. [Wikipedia]
