The Dewald model B512 was a catalin clock-radio with the speaker mounted on the top.
The shouldered cabinet is the same as the Dewald A502, but with speaker grill slots
cut into the top and a clock in place of the front speaker.
It included brown pinwheel catalin knobs.
I think the only two catalin clock-radios ever made were this B512 and
a Dewald "Harp" version that included a clock.
