 That cabinet looks familiar for some reason, I think it's a factory cabinet, but it's not a Philco cabinet, it is not a 620 though, the escutcheon displays a shadowmeter. To me it looks a lot like a Sparton or an early 1930s Bosch. It would be interesting to have a look at the set from the rear, if there were an shims or extra holes drilled to hold the Philco chassis in there then it probably a frankenradio. There was a company in New York that used to put mismatched chassis and cabinets together, particularly during the war years when you could not buy a new radio, some are rather well done like the McMurdo-Silver chassis in an American Bosch cabinet that Bruce has.
