Looks like a broadcast monitor, the kind used by TV studios. And yes, by the 70's they were already all this size, intended to be mounted in racks.
More likely it is a repurposed CCTV monitor, that looked like this since very early too (In the 90's worked in place that had a very old CCTV system, from the 70's, with the giant cameras, and the displays were basically this size and format.
There were other very small TVs too. It's not like we still used vacuum tubes to build tvs in 76.

Except for the picture tube itself, of course! (Broadening the definition a bit, perhaps.)
I have a Panasonic CCTV that looks exactly the same as this one. It was $27 plus shipping on eBay this year. It uses BNC connectors instead of the later consumer-standard yellow RCA.
