Kuibyshev Hydroelectric Complex Construction Badge, 1957.
Brass, enamels; measures 22.3 mm tall, 27.4 mm wide. Pin back version featuring Moscow mint mark "MMD" located in the lower in the lower left segment of the reverse (as opposed to the right side).
In outstanding, excellent condition. The enamel is perfect, free of any wear visible to the naked eye. The gilt finish is likewise perfect and bright on both sides of the badge.
The badge continues the series of the earlier NKVD construction awards such as Moskva - Volga Canal, Dneproges, Ukhta and others. It was awarded primarily to prison guards and managers who supervised construction of the huge complex of hydroelectric dams on the Volga near Kuibyshev. Like most other large scale projects of the period, it was built almost exclusively by prisoners. The construction started in 1937, then was put on hold in 1940 and resumed in 1950. Its final stage was done by the inmates of the Kuneevskiy Correctional Labor Camp.
