I just won a Zenith roundie color set ,on Ebay. It is a 24nc31 model, making it a 1966 model(probably the last year you could get a roundie Zenith).
Thing is, no one else seemed to want it. it looks pretty good from the picture, with a little bit of de-lamination, but not too bad. it also appears complete. I paid a BIG, $15.50 ,for the set. This means, of course ,another "Tv run" soon, this time to Indiana, to get the set.
