USA: Radio Catalog for the radio manufacturer Polytechnic Research & Development Co, Inc. (PRD); Brooklyn, NY
Here you can view a Radio Catalog for the selected Manufacturer/Brand on ONE page - and may use «Ctrl-F» to find models, but we recommend the normal search because the
sorting here is done by computer without human intervention.
Be aware that this page is static and renewed only once every 10 days. You are better off using the dynamic page for the Radio Catalog.
To get a list by date, go back to the search page (HP) and use the "Advanced search for Antique Radios" by typing a manufacturer/brand in the corresponding field. To get the Picture Gallery, also check the green camera symbol. [modelindex.cfm-en]
