Yeah, blank here too. The switches and especially the tuners scream late 70s/early 80s "Lawsuit" JapCrap to me, exactly the same pattern on my 1981 Aria TSB-400 but I've seen them on other brands like Columbus & Avon etc.
It's unlikely to be a Matsumoku-built bass - if it were I'd expect to see the neck plate stamped 'STEEL ADJUSTABLE NECK'.
Any chance of a better shot of the headstock? preferably in daylight & at a bit of a shallow angle. It *might* throw up something hiding under the paint.
