It looks to be a power tuning if not a remote model. I'd guess it is later in the tube era maybe early SS. I know I've seen that control panel at least once before, but my mind is not giving me a chassis number....A friend is interested in buying it and wants to know if it is tube or SS.

CTC-21. 1967. One of RCA's best chassis, tell your friend to snap it up. I've been trying to find a 21 for ages.

See the brochure in this thread, your set is on page 9.
