The chassis, and possibly the whole set, was manufactured by Ozarka Radio (or Belmont), according to the green plate, but they don't give the model number. The extra control above the dial does not belong there so ignore that in your search. Freshman didn't have anything to do with this set, obviously someone bought the rights to use the Freshman name, or the escutcheon came off of a later model Freshman set made after they merged with Freed-Eisemann, those sets were built in a plant in New Jersey, not Chicago which was where Ozarka was based.
