This radio has the oval "racetrack" dial and is highly sought after. The functions of the 4 round knobs from left to right are On/Off/Volume, Tone (2 positions), Tuning, and Function. The radio has 5 pushbuttons on the lower part of the brass escutcheon. The Function knob on the far right selects either Shortwave, Standard Broadcast, or Automatic that activates the station presets. I had to pull out very slightly on the tuning knob to tune the radio smoothly (otherwise it would sometimes catch before moving again).Please look at all of the pictures for more detail.
