Wow! I didn't even know Ozarka even existed long enough to make a radio like that! I've run across their 20's offerings over the years, but never later than the mid-20's styles.

Jayce;
  Ozarka Radio lasted up until around 1932, if I remember correctly, and manufactured a lot of AC operated TRF cathedral and tombstone sets. I read an article in the AWA Old Timer's Bulletin on the company and in spite of the name their manufacturing plant was in the Chicago area. Ozarka was rather like Belmont radio, they made a lot of their money manufacturing private label sets for store chains. One interesting thing of note is that some of their chassis were made out of a cast aluminum rather then from stamped or folded steel.
