  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-617B Rhythm Maid and sets a price of $ 125.91. 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.
