I had two great-aunts, now deceased, who had a Sony color portable TV similar to yours. Theirs was a 12-inch all-channel TV from, IIRC, the late 1960s or maybe the early seventies; I'm not sure, but since it was all-channel I'd guess 1970s. Their set did not have remote control, that I was ever aware of, but since they were always within a few feet of the set when watching it they really didn't need a remote. They lived in a third-floor apartment in a Cleveland suburb; the TV worked very well, as it should have in a third-story dwelling (their building did not have any kind of master TV antenna service, and this was long before their area ever had cable), using only its built-in VHF dipole and round UHF antennas. I don't know what became of the TV after they died, but I do hope it found a good home since it was working extremely well as long as they were alive and needed no service, that I was ever aware of.
