  • Notes
  • The Harrison Wholesale Co., Chicago offers on page 158 of its "Mid-Summer 1936 Electrical Radio Catalog" No. 239 for dealers the following Arvin Car Radios with chassis 28: 28-DM for $ 49.95 list price, dealer price $ 29.97 or $ 29.37 net. The cabinet has the same size as the models 18. The same radio as 28-EM has a 8 inch separate loudspeaker and is otherwise the same - with streamlined remote control and indirectly illuminated airplane type dial. Listprice $ 57.85 / 34.74 / 34.02. Harrison offers also the model 33-DM and 33-EM, both with metal tubes. All are with single hole mounting. Chassis cases are in Benton Gray Morocco, 28 and 33 with chromium plated speaker grill.

    Vibrator for +B. Vibrator for +B. Rider's shows that the chassis type 28 has been published 1936 (or before). The Belknap Hardware & Manufacturing Co. Catalog of 1937 names this model on page 1063 with the model E-18.

    The whole 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.
