Crosley 628-B, "The Sixer," 1939
Approximately 11-3/8 inches / 29 cm wide.
Tube complement: 6A8G mixer/oscillator, 6U7G IF, 6P5G detector, 6F5G 1st audio, 6K6G audio output, 2W3 rectifier.
Molded into the Bakelite, on the inside front of the case (visible only when the radio is disassembled), is a capital letter 'F.' This would be unremarkable, except for the fact that the F is rendered in the unusual and distinctive typeface used by Firestone. I'm not aware of any connection between Crosley and Firestone. Crosley was a "real" manufacturer that made its own radios; Firestone was a house brand, manufactured by Belmont and other OEM suppliers. I would welcome any comments or explanations for this alien F.
Flash! Famed plastic-radio collector and expert Steve T. Davis has suggested that Firestone Tire and Rubber Co. may have been a plastics supplier in addition to a consumer of OEM radios. So we may have a case here of Firestone supplying molded Bakelite radio cabinets to Crosley while buying completed radios from other manufacturers to sell under the Firestone name.
Above, the chassis. At left, from a November 1938 Crosley advertisement. (The ivory set mentioned was painted Bakelite. I've never seen a red Sixer, so I'm left to assume its red color was painted on too.)
