RCA TM-21B Color Monitor

[vintagecollect]

anyone knowing of these were used in most early color tv stations?? The tube count is high, complicated set. Used very good color demodulaion and other advanced circuits? Henry kloss used one of these when he was designing the advent videobeam. It shows his lab setup with this monitor, screen size is adjusted to look like a rectangular picture, but screen is definate roundie and cabinet the same. Station indicator is projected in large white numbers w/ black background from square window above crt. Does anyone have one besides the museum?? Color reproduction must be excellent. For ultra accurate NTSC color?
