Nice Ad for Radio!
 

Look at what I found on the back cover of the May 1937 issue of "The Etude" magazine... It was too big to scan properly!

Cool! I have the little brother 37-10 model with the same nifty tuning mechanism. I think it works a lot better than the wacky cone-centric preset system they tried in 1938.
First antique radio I ever got :)

Nice radio B,
Philco made this one first? Grunow had one too.
I have a Motorola 12Y, also from 1937.
The teledial power tuning still works and so does the radio, without a recent recap.

I think the Philco uses a different mechanism than the Grunow.
Here's an excellent article on how it works: http://www.philcorepairbench.com/autodial/index.htm
