sonora-rad: Ch= KFU;
I have just sent 3 pictures of my Sonora Model 252 from 1941 to Radiomuseum.org. The chassis is exactly as described in Riders. The size of my set is: 7.25 inches long by 5.125 inches high by 4.25 inches deep. It does weigh in @3.5 pounds. I do suggest you put this information on the KFU chassis (Model 152)
You can clearly see a picture of this radio in Mark V Steins "Plastic Radios" on the bottom of page 217.
