No doubt about it, it's a Frankenradio.

Notice how crudely the opening for the dial was cut into the wood.

Yes, someone added that Stromberg-Carlson chassis after the fact.

That's what I first thought but I'm not so sure that it is that crudely cut, if you look at it up closely is has a routed edge. I think that what makes it look crude is that the rubber mounts under the dial mechanism are shot so the dial is listing over to one side, it creates a sort of optical illusion. It is also an octagonal dial behind a hexagonal hole so the corners do not line up, but the hole itself look fine. Whether someone building the cabinet screwed up or whether someone fitted the wrong chassis in there it doesn't look right. I don't know if the Radiobar company used only Philco chassis or used ones from other suppliers. What American makes used hexagonal dials?
