... ADF radios used AM freq. band. Knob on the right tunes the radio station and (missing) knob on left tuned the antenna for direction....
2" seems a little small for a car... but about right for an airplane.
Dial for AM. Makes sense. Motorola has always been big in radios. Looks like there might be 2 threaded holes to mount the dial to a dash. Maybe the other side large hole held the rotating cable to the box where the tubes of the tuner/amp of the radio was. Lower mid opening would be for a socket for a backlight.
Here's some more info about that item.

We'll let this one cook in a vacuum a bit longer, .see if anyone else figures it out.
