Here is the Military Driver Badge. This particular version was once a very late period Tsarist Badge which was crudely made with paint in place of enamel. The crown was removed (either before or after issue) and was worn in the period just after the formation of the "Fatherland Front".
This Driver Badge was constructed and issued after the formation of the "Fatherland Front" with a slight increase in production quality as this badge is once again enamelled.
