Unusual Capehart!
Your set should be 1952-54 or later, because that was the time frame for Capehart's big switch to that kind of molded plastic tube mask. However, most Capeharts of the era had a big escutcheon in the middle of the control panel, with the minor controls, like Horizontal, Vertical, etc. on it. Yours does not have that, which may point to a later year.
But there's something strange about that, too - 1954 was Capehart's last year for heavy involvement in furniture-grade cabinets. Beginning in 1955, they started pushing "consolettes" (boxy TVs sitting on wrought-iron or other spindly legs) and cut out pretty much everything with doors. They still made consoles, but much more ordinary ones than before. It seems pretty obvious to me that they were pushing for mainstream sales, with mainstream sales figures, concentrating more on mass than class.
Your TV is somewhere in the middle of all this - it is obviously fine furniture, not a "mass market" design at all.
I will keep researching, and hopefully we can come up with a year. If you have a model number anywhere on the set, it would help enormously.
Nice set, and nice project!
