The red telephone includes a Nazi party symbol and Hitler's name engraved on the back. Occupying Russian officers gave the phone to a British officer, Sir Ralph Rayner, during a visit to Hitler's bunker in Berlin. The phone was used in vehicles and trains as well as Hitler's field headquarters.
Kornfeld says a porcelain figure of an Alsatian dog, also owned by Hitler, also sold Sunday to a different bidder for $24,300.
