The Sparton 409-GL was the last of the Walter Dorwin Teague mirrored radio designs for Sparton and boasts a small seven sided beveled mirror as a faceplate. The dial numbers are etched into the mirror glass from behind. Originally sold for $18.95 as a "Second radio for the home", it is built around a four tube design and requires a long wire antenna for satisfactory reception. Tuning covers the AM Broadcast band only and the only knobs on the front are the On-Off/Volume control and the tuning knob.
This set is as of yet, unrestored cosmetically or electronically and has the "curtain burner" resistive line cord. I'll post new pictures when it has been restored.
