[Phlogiston]

I'll get some pictures today of the console. I believe that it has the very same speakers.

It might be a little later in the day. I have to go look at a collection for a charity today.

I can think of one other radio in my display with a similar "why" as to having 2 speakers and that radio is the much more popular Zenith 760, photo below.

The radio I pictured above and its various chassis are narrower than the subject chassis. So it is just very similar - probably related.

Note too the similar paint selection on the zenith chassis. Maybe this was an early 1930s "style" with no other explanation.
