You nailed this one clean on the spot:

The radio pictured, Model DAC90A introduced in the mid-to-late 40, is featured on the opening page as "The most successful radio set of all time."
I don't know about that, but here's a short quote from the site: "Probably over half a million of these particular little sets were sold, with the cabinet design having only minor changes for something like nine or ten years. The initial models were only in black bakelite, but later versions were available in brown, walnut (by far the most common colour), ivory and white. I've never seen a truly white one- only ever ivory. There have also (allegedly) been factory-produced painted cabinets in a dark cherry red."
Tons of good reading there.
