It's strange that Dumont, the Cadillac of Televisions, went with such an oddball CRT.
Not only is it not Aluminized, it's also made of thin glass and has a bulbous pre war shape, it's only advantages I can see is it's lighter, and they didn't seem too concerned about weight.
Others like Zenith and GE were using Aluminized tubes as least as far back as 1948. I wonder who had the Patent on that?
