This massive 11-tube console was probably one of the nicer Firestone consoles made. It has an eye tube, dial-matic station selection, and a great looking cabinet.
I've never seen one of these, and there is no model number listed on the ad. A viewer has suggested this is probably a model 7423-4, or R-308 (Riders Volume 9, pages 7 and 8).
The radio did not make it into the Spring-Summer 1938 catalog, so possibly it was discontinued early on.
We've finally confirmed that at least one exists, as a photo was posted to the gallery here.
