Posting a photo of the chassis may help, but if it's like the Radio Attic set it looks like it could be either a Wells Gardner, a Continental (later Admiral) or a Belmont, those were the big three in Chicago that manufactured private label radios for stores, with a few being made by Stewart Warner (particularly for Sears), but I don't think it's one of those. By the styling, and double ended octal tube choices, and inclusion of a 6H6 double diode, I would call it either a 1937 or 38 model. Does it have a glass dial or a plastic one? Lighted pointer from the rear are unusual, Rogers used them in a number of their sets, particularly Deforest-Crosley, in the U.S American Bosch, Midwest, Majestic (post 1934), and I believe Scott also used them.
