This is a difficult model to find and likely to be a low production item as it is not listed in any of the service data indexes.  Dubbed the "Peter Pan" by Westinghouse, it's a very heavy radio for its size. Other than the "U" shaped plastic cover that wraps around front to back, the rest of the case is made of heavy case metal. The bottom section comes off and that's the battery compartment. Has 4 subminiature tubes. It's the heaviest of all the coat pocket size subminiature tube radios. The bottom "kickstand" also serves as a handle and can be retracted. Battery requirement: 1-45 volt "B" battery, 1-1.5 volt "A" battery. Weight: 2.25 lb. without batteries, measures 6X4X1.75".
