This paper model is a simple T-12 (or T-1-12), a Soviet medium tank, the papercraft is created by Dragos, and the scale is in 1:33. The T-12 was the first tank project of the factory, the type of the mass production name is T-24. This was a larger version of the T-18, with a more powerful engine (the T-18 was based on the Renault FT-17).
Only twenty-four tanks were built, and none saw combat. This was the first tank produced at the KhPZ factory in Ukraine, which was later responsible for the very successful T-34 and T-54 Soviet tanks. The T-24's suspension was used successfully in the Soviet Union's first purpose-built artillery tractors.
The T-24's main armament was a 45 mm gun. It had a ball-mount 7.62 mm DT machine gun in the hull, another in the turret, and a third in a secondary turret atop the main turret. The tank was well-armoured for its time, but suffered from problems with the engine and transmission. [Source: wikipedia]
