Looks like a Hofner to me, they did solid bodied basses too - [url="http://www.vintagehofner.co.uk/gallery/gallery2/bas.html"]http://www.vintagehofner.co.uk/gallery/gallery2/bas.html[/url] - see section "HOFNER SOLID BASS GUITAR (VERSION1)".
I'd guess it's one of the first series, but with the longer horns - [url="http://www.vintagehofner.co.uk/hofner/basses/bas17.html"]http://www.vintagehofner.co.uk/hofner/basses/bas17.html[/url] ("It appears that, after a year or so, the body was changed to a "Strat" type body (but still with the "set-in" neck)")
Headstock shape looks right, truss rod cover looks right, square tuner buttons look right, rectangular angled pearloid control plate looks right, can't really make out much else.
