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
