ZIS-21

Produced 1939-1941 (1946-1952 it was produced under name UralZis-21A). In 1952-1955 UralZIS produced little bit modified model Ural-352.

This truck is based on ZIS-5 but its powered by gas generator (firewood was used to power the car). Because of this it has low power and speed, it is difficult to service and not so easy to start up. But because the lack of gasoline in some north regions this truck was unsubstitutable.
