There are very few auto radios made prior to 1930 survivning. The set you have was made by the company that Philco finally bought and used the Transitone name that came with the deal. I have a friend in Houston, Texas who has chased this history a long ways. The original Transitone sets had a very crude control head. It had two controls that came through the dash panel, so I understand. My eyes have never beheld one.

The set that my guy in Texas found was one offered by Delco-Remy, manufactured by General Motors Radio Corp., in Dayton, Ohio. Like all of the auto sets made then, it used the car's 6 volt system for "A" power, and batteries for "B" voltage, often in a box, dropped through the floor boards. The Delco set he has is in his 1930 Cadillac V16 roadster.
