In around 1935-1949, Mission Bell Radio Inc. made quite a few radios (now they are all very rare) for Sears. These radios were sold by Sears under their own Silvertone brand, and were available only in California. It was normal practice for Sears to provide warranties and service for all Silvertone radios at that time. Silvertone Mission Bell Radios, however, were completely different in that Mission Bell Radio Inc. provided the warranties and repair service.
           This explains why we couldn't find any information (manual, model and chassis numbers, schematic etc.) in the Sears Nomenclature Index (the complete list of model numbers) or in the Sears Repair Manuals (the service instructions for each Silvertone model). Most likely, Mission Bell supplied authorized local repair shops with their own service manuals and other service information.
           From 1928 up to 1949 Sears Nomenclature Index mentioned only a few models made by Mission Bell.
           09.08.1938 - Chassis 113.972 - Models 3972, 7806
          
           09.18.1939 - Chassis 113.414 - Models 7807, 7808
           03.28.1940 - Chassis 113.504 - Models 7814
           For chassis shows below in the Sears Nomenclature Index models number were not assigned and no additional information were provided.
Chassis numbers:
113.383, 113.395, 113.400, 113.407, 113.411, 113.639, 113.639A, 113.949
