The Arvin model 627 Rhythm Master with 7 3/16 inch dial from Noblitt-Sparks covers 560 - 171 meters (Green, 535 - 1750 kc), 176 - 52.2 meters (Yellow, 1700 - 5750 kc) and 54.5 - 16.65 meters (Red, 5.5 - 18 mc). One electro dynamic speaker 10 inch. 3-gang condenser, continuous tone control. Cabinet in rich-grained walnut in combinations with pencil-striped mahogany and satin wood.
  
  Rider's shows that the chassis has been published 1936 (or before). The Belknap Hardware & Manufacturing Co. Catalog of 1937 features this model as E-627 Rhythm Master and sets a price of $ 134.10. Pages 1053 to 1056 show a whole model family for "Rhythm". The family is in that catalog shown with a prefix E- whereas schematics and other ads show the models without this prefix. The "E" could refer to this catalog only since also a storage battery U17 or U175D is here called E-U17 and E-U175D. But we have to add the prefix so that users do find if they put it in.
