Mike,
Unless they were sealed up in a crate for almost half a century i doubt any of them are going to look amazing, the very best may have gone through a refit anyway. The thing you want to be most fussy about is the state of the bearings, as that will be the hardest and costliest thing to sort right, everything else can be replaced or reground.

I've seen a few as-new secondhand lathes that friends have bought over the years. Tech college or high schools are good sources. They spend most of their time not running. Some that get sold off are in as-new condition.
Likewise, lathes that have been in say an auto-electrician workshop, used occasionally for truing up the odd commutator. I know one old auto-electrician locally has an ML7 from the 1960s or 70s or so that is in as new condition sitting in his workshop rarely used. He even covers the ways with oiled ricepaper between uses. (Got my eye on that one!)
But of course, examples that have been flogged to death in a production environment churning out widgets by the gazillion are not the same story. Nor machines that have been used and abused by all and sundry in a busy fabrication jobbing shop where everything is covered in angle-grinder grit and plate scale and nobody is responsible for ever cleaning the machines. Seen a few shockers at those kind of auctions.
And as far as bearings go, well most lathes today are taper roller headstocks so no big deal to obtain or replace the bearings. But I reckon a lathe that has worn out a set of properly maintained roller bearings probably has some serious wear elsewhere too.
If you look out carefully and bide your time, the deals are out there. Just don't get sucked into the excitement of bidding on the wrong machine for the sake of getting "something".
