I believe that Sony used some of their portable transistorized TV sets as monitors, equipping them with SO239 UHF connectors. I recall having one of those as well.
Sony's CV and AV series reel to reel portable video recorders used one of those. It was black, and had Rf input, UHF connector, a 14? pin rectangular Honda plug, and a slide switch for TV/monitor. In 1971, I once "repaired" one of the college's ones by sliding that switch out of the middle position :-)
I got one of those at a flea market, and that was what I had for my TRS80.
