Great to see this! When you first see one of these (which I did in 1965 at the NY World's Fair), you might suspect it's transistorized, but no, it's a tube room heater.

Regarding the mirrors, I suspect the coatings will be peeling like the one that was at ETF, and if they aren't, I would really hesitate to try cleaning the coated side.

Do you know if the three tubes have red, green and blue phosphors, or are they white with the color totally due to the mirror coatings? I can't remember.
