1940 - 1941
MERCURY MODELS

Apparently in 1940, Midwest introduced a new line of radios at an even lower price than their standard lines; The Mercury.

These radios used the existing lineup of 1940 console and table model cabinets outfitted with a special two band 15 tube chassis which was inexpensive (cheap) to say the least. Out of the 15 tubes 9 were triodes, dual rectifiers and a tuning eye help to complete the tube count. 
The band switch is a slide type switch located on top of the chassis which means the operator had to reach behind the radio to change the band.

Major features are the Organ-Fonic Tone Filter speaker enclosure on consoles and a new "Bi-Focal" style tuning eye which displays two shadows instead of one. This really didn't do much good as half the eye tube is covered by the metal bezel on the cabinet. I doubt that many of these sets exist today.

I believe this is a late production Mercury as the cabinet is a 1941 series.

Minor changes to the chassis are a variable tone control in place of the key type controls and a simple change in the tube line-up.

This small console cabinet measures only 33" high, 
26" wide and, 12" deep. I have to stoop down to read the dial.

Price was probably around $50 complete with tubes.
