Meazzi Guitars were produced in Milan, Italy, in the 1960s by the Meazzi brothers. The Meteor Bass was produced between 1964 and 1969 and came in one and two-pickup versions, the Meteor Bass I and the Meteor Bass Extra respectively.
The bass appears to be very thin-bodied, and has some pretty heft hardware on it - check out that bridge cover - but controls-wise the bass is quite conventional, unlike some of Meazzi's other guitars with sliders for treble and bass and a quick silver kill switch activated when the instrument is put into a horizontal position.
However, is it just me, or does the action look a little too high on this bass? (And why was that model's head cropped off in the above pic?)
