  • Anotaciones
  • Vibrator for +B. Vibrator for +B. Rider's shows that the chassis type 33 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 and E-28.

    The whole family is shown in that catalog 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.

    The Harrison Wholesale Co., Chicago offers on page 158 of its "Mid-Summer 1936 Electrical Radio Catalog" No. 239 for dealers seven Arvin Car Radios with chassis 18, 28 and 33: Two type 33 are: model 33-DM with a Listprice $ 54.50, dealer price $ 32.70 and net 32.05 and 33-EM same with a separate 8 inch speaker for $ 62.85 / 37.71 / 36.96 including metal tubes for both models. All are with single hole mounting. Chassis cases are in Benton Gray Morocco, 28 and 33 with chromium plated speaker grill.
