This is the Airphone Radiotrola Baby Grand Portable which was advertised in October 1924 as the Monodyne Baby Grand and in November 1924 with a name change to Radiotrola Baby Grand.
These ads in Radio News are the only ones I have found and this radio is one of two that have seen.
This company later moved to Brooklyn, NY and became Somerset Radio selling conventional TRF sets.

Lets keep this going.
These are the Moore Radio Demon radios made by Electric Service Products Company of Chicago which was established in 1910.
These were distributed through the "Chicago Daily News Radio Laboratories"
The one tube regenerative tuner is Model C which retailed at $32.50, , the one stage amplifier is Model D which retailed at $18.50, the two stage amplifier is Model E which retailed at $35 and the three tube regenerative receiver was Model Y which retailed at $70. These came to me from various sources a few years ago They are from 1923.

I'd like to see this thread get going again.
Here is a Resodon manufactured by Paul Niehoff Co. of Chicago in 1922. A friend has the one shown in Vintage Radio - the only other one we know about. The two are different models - both from 1922. Construction looks very complicated as there are actually a cabinet and a sub cabinet. It probably wasn't a profitable set.
I recall that Niehoff also made ignition parts for automobiles.
Ads are seen in the Dec 1922 ROTARIAN and Sept 1922 RADIO and probably a few other.
The company exhibited at the Pageant of Progress show at Chicago in as described in the
August 5 1922 issue of MUSIC TRADE REVIEW. It probably disappeared soon after.
Any more of these around?

Nice set!

Any pictures of the inside, showing the component layout and wiring?

Al, That crystal set is awesome. It almost looks new! I assume it works, have you actually listened to it?

Terrey:
I didn't get any inside photos of the Resodon
I probably should have.
I had another flood after the last big rainstorm and I kind of got sidetracked. It is very difficult to photograph. It's really quite a monstrosity.

Keep the early stuff coming on here!!
