Yes,
U.S. Radio & Television made the Gloritone and Apex sets plus a lot of the Airline sets for Monkey Wards. They were located in Marion, Ind. before being bought out by Grunow in '33' located in Chicago.

Ah, so that's what happened to US Radio & Television. I also have a Mantola with the Apex 27 chassis in it from the 29-30 period. The Gloritone is working decently now, but the speaker is touchy and develops cone rub unless you have the volume and tone adjusted just right.
