Silvertone 6407, 1940 Tube complement: 12A8GT mixer/oscillator, 12K7GT IF, 12Q7GT detector, 35L6GT audio output, 35Z5GT rectifier. Approximately 8-1/2 inches / 216 mm wide. Just like the Silvertone 6405, this radio has the pilot lamp behind an opaque dial scale.  It also has a similar upside-down chassis, with the same tube complement and circuit.  The difference is the addition of the four pushbutton mechanical station presets.

This label, affixed to the radio's back, says that it was repaired on July 1, 1947, by Bob Uhl Radio Service in Tiffin, OH.  Notice the Silvertone paper labels on the original Silvertone tubes peeking out through the back's slots.  Like the Airline 04BR-421B and others in my collection, this radio is still operating on its original electrolytic power-supply filter capacitor.

From the 1940 Spring/Summer Sears & Roebuck catalog.
