Interesting radio! I know some companies made radios to put on refrigerators. Westinghouse was the classic example. (And one I've half wanted. Except I don't have a Westinghouse refrigerator--the "right" home for it. Plus, AM radio is pretty lackluster these days, unless you like far out political commentary!) But I'd never thought of a radio built into a refrigerator before.
I think some modern refrigerators have built in computers for Internet--the "radio" of today, I guess. Funny how old things become new again....
