Looks like the hallway of an old R&D lab. Not the old RCA Sarnoff Lab, they built that place around WW2. But he still had an office at Sarnoff until the mid 80's, but I don't remember ever seeing him there.
RCA Labs had a small display/museum of early color TV. One of the items was a prototype of the shadow mask color CRT. They threw it together late one night, so they could show it to the FCC the next day to convince them to forget about that CBS sequential color wheel thing, and go with the NTSC color system. The CRT looked like an oscilloscope tube, and about 7 inches diameter round. And had a smaller rectangular region where the color phosphors and shadow mask was mounted inside. A proof of concept demo unit. I don't remember seeing complete sets there, not enough room.
