I also have an Emerson 508 (battery only) and a Motorola 5A7A (three way) that use a 67 volt B and a D size A.

EDIT: nabbed photos off epay. empty box lol.

two 45 volt "B"s and two 4.5 volt "A"s. hmmmm.......

The radio was made by Warwick. I wonder what battery life was like? Using a 9 volts "A" source makes the switching circuitry simpler between line and battery.
My luggable Emerson 523 uses the same battery compliment.
