  • Notes
  • This 1937 model must have been released in (late) 1936 to get the X-mas sales. It was advertised with Shirley Temple promoting the Radio with reference to her motion picture "The Bowery Princess" of 1936. Further: the schematic is found in Rider's Perpetual, vol.7, which covers End 1935 to End 1936, not later. All that justifies the dating 1936/37
    Beitman shows Grunow chassis: 12B, 12W for models: 1291, 1297 for the same schematic. The same is for Rider's page 7-35 for General Household. One might think both chassis are used for both models but we believe it is meant only that the Grunow chassis 12B is used for model 1291 and the 12W chassis for model 1297. Therefore we show two models, not 4 as other sources. See this article containing Teledial models. Also Teledial models of other brands are covered. In particular the nine 1936/37 Grunow models presented in "Radio Retailing", March 1937, are linked.
