An extremely fine Soviet Order of the Red Banner of Labour here, early and desirable "flatback" example. Serial number is present on the reverse - 272,769 - along with maker's mark. Mount is magnetic, suspension ring is uncut. Beautiful piece. 
 
The Order of the Red Banner of Labour was an order of the Soviet Union established to honour great deeds and services to the Soviet state and society in the fields of production, science, culture, literature, the arts, education, health, social and other spheres of labour activities.
