Early-1970s turntable with the pivoted Zero-100 tonearm (tangential tracking geometry).
Idler-drive turntable: the idler wheel, main bearing and motor mounting decide the price far more than cosmetics. Check the platter spins without rumble at both speeds and that the original plinth/arm are present (a missing SME arm or a non-original plinth can halve the value).
