Agree with Chuck, this was added later on and is, most likely, a phono jack.
I've been restoring a monster Philco 680 recently, and it also had a switch and RCA jack on the back of the chassis like this. I suspect this was done somewhat frequently to radios after they left the factory, as some customers probably wanted to be able to play records through their radio but chose not to purchase one of Philco's wireless phonographs which they made between 1939 and 1942.
