I can't find my Slussders book right off hand.
It is an eight tube set, but it has a very weak power supply, Zeniths are not known to be robust in their power supplies and it may have all rubber insulation which has probably crumbled by now, so it may take extensive rewiring. The rectifier is a major problem 6X5G as they tend to short and take the transformers out as well. Yes I would ask to inspect it, rather than take the sellers word that it works. If it looks like the cabinet is in good shape that's a plus. Its sounds like the price is a little high to me. But then most Zeniths as you say are overrated.
Have him let you smell the inside, if it smells of burned parts pass, unless you know for certain you can repair any defects that come along. If it plays then give him a counter offer of $130-$150 because of known weaknesses. I am not an expert on Zenith but unless its a 10 -12 tuber or Rare set the price is a little too high. JMHO
I went on the web after my posting and you might want to look at this. By the way that is a georgeous set.

Looking some More I saw two selling prices which floored me. But they were completely Restored mind you. $800 -$1100
