1955-1959 Gene Krupa model Radio King from Slingerland. It features the Streamline lugs, Clam Shell throw off and single flange hoops. The sold shell & reinforcement ring is in excellent condition the black diamond pearl finish ply shows some slight wear as does the nickel hardwear but both are terrific shape considering its age. This drum has a sharp attack and a deep tone. Any excellent addition for any collection.
