I'm not sure it's worth a 2h drive to have a look, but I wouldn't obsess too much about wear of the ways. that may be wear or it may be lack of staining from where the carriage runs, either way any lathe that old is going to have some degree of wear. I'd be much more concerned about wear in any of the screws (lead, cross, compound) and tooling. those are things that will affect your ability to use the lathe, way wear is a minor irritant in comparison.
