A good looking Soviet Guards badge, post war manufacture, with a (likely) replacement spinner on the reverse. Condition is as depicted in photos. Doesn't feel cheap like the very late-Soviet produced badges, I would imagine this badge was produced in the late 1960's or early 1970's.
 
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.
