STZ-3 Tractor

The STZ tractor made in the Soviet Union in the mid-1930s.  This is a 3d printed HO scale model

They were agricultural tractors but due to the war situation hundreds were shipped off to the front.

The 122mm D30 howitzer was often towed by this tractor.

These are 3D printed models that are sold by Fidelis Models under the name "Filament Fighters."

Enclosed cabs were necessary due to the extreme cold in the Soviet Union.

Many of these were captured by the Germans early in the war and pressed into service with their forces.
