A good looking Soviet Guards badge, post war manufacture, with matching aluminum spinner on the reverse. Some cracking is present on the star in the center of the badge which is visible in photos. 
 
Guards units (Russian: Гвардия, romanized: Gvardiya) were elite units and formations in the Soviet Armed Forces that continue to exist in the Russian Armed Forces and other post-Soviet states. These units were awarded Guards status after distinguishing themselves in wartime service, and are considered to have elite status. The Guards designation originated during World War II, its name coming both from the Russian Imperial Guard, and the old Bolshevik Red Guards.
