Hi there everyone,
We're basking in+20 C. weather here in the Southern Hemisphere.
Reading your request for information on this radio rang a bell for me.I have recently taken delivery of a  good book "The Auto Radio - a Romantic Genealogy " by Donald Matteson.The picture of the set you are enquiring about is ,to me , strikingly similar to the illustration on page 119 of that book showing a 1933 Ford dashboard  "showing the famous  Glove Box radio". However Mr. Matteson identifies it initially  as a Grigsby -Grunow. But according to the text the first 25,00 of these were built by Grigsby- Grunow but toward the end of 1933 this company filed for bankruptcy leaving Ford needing another 30,000 units ,whereupon an order was placed with Zenith to produce the balance.So , I guess, depending on whether yours is an early or late set  it could be,if Mr. Matteson is correct,either a Grigsby -Grunow or a  Zenith.
If I were more computer literate I would attempt to post a copy of the illustration on line.Maybe my granddaughter will be able to help
