Rudzutak Advanced Training School for the Security Command Personnel of the Roads of Transportation (Railroads), 3rd Graduation Class, #26, 1928 issue. A beautiful, very elaborately designed piece in hallmarked silver and enamels of literally Faberge quality. In excellent condition.
A very small number of these badges were ever issued and only a few are known to exist today. Many of the high level state security / law enforcement officers who had graduated from the Rudzutak School became victims of purges during the 30s. An arrest of the original owner usually led to the badge being confiscated and destroyed. Incidentally, Rudzutak himself was arrested, tortured and executed in 1938 thus making him an "enemy of the people" - and making ownership of the badge bearing his name a very risky proposition!

Highest Diplomatic School graduate badge, late 1960s through 1974. Exclusive college for espionage agents and children of Soviet elite. In excellent condition.
