I don't think you could lose money at $600, but there are a number of things that would concern me. One, the QCGB has been off and they reinstalled using only two bolts, of the wrong kind. Two, the lever for selecting power feed to the apron or cross feed (or neutral) is missing, as is the power feed clutch knob/lever. On the plus side, two chucks, plus a dividing head help a lot if you had to part it out. I'd rather buy a complete lathe (vintage) that isn't working than one missing almost any parts as they can be incredibly hard to source at this point.
