I also had a quick look at Sony practice, as probably representative of Japan Inc. It seems to have changed from “X” to “Q” somewhere in the mid-1960s. The CV-2000 video recorder used “X”. But the transistor monitor interface in the CVM-2300U domestic receiver-monitor (of c.1965) used “Q”, as did the TUM-100 outboard TV tuner, which was intended to be used with the CV-2000.

Cheers,
