Looks like a 70's Univox - which was an early Japanese maker.
I have several of their guitars including two Les Paul models. They have the same 3 ply binding around the headstock, same tuners and truss rod cover - but it looks like the pickups have been changed.
They are on the low end of construction (bolt on necks) but they actually sound quite good. Going price on them here in the US is about $250 - $400. I wouldn't pay more.
