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?

It's an oddball because Dumont made their own CRTs. My guess is Dumont was still using their pre-WWII (pyrex) tooling and methods for a while post war.
IIRC Dumont's CRT tech was state of the art pre-war (they had the biggest domestic production CRT 14"). Post war I think they were the first with a 20" CRT so they still lead, but as others made advances they were slow to latch on and mix in other's tech.
