This was Zenith's top of the line, non-Stratosphere model for 1937.  It featured 12 tubes, push-pull 6L6 audio output, 4 bands, target tuning, and a backlit dial which only illuminates the band that's currently selected.  Audio output is 17 watts.  It really does shake the house.  My example has the original finish, though the top is heavily scratched.  The grill cloth is original as well, and it is only missing one knob.
