Hub Label Anomaly!
Let me begin with a confession....building wheels is one of my first-favorite things to do!
Like many other wheel builders, I take pride in orienting the rim to the hub in what I understand to be the generally accepted conventions. In short, where labels exist, I orient the rim so it's label is readable from the right (drive) side of the bike. Hub labels are readable through the rim's valve hole when standing over (or behind) the bike.
Here is an example of what should be visible on an older Campy rear hub when looking through the valve hole. Note the text is right side up when standing over (or behind) the bike.

Now take a look at that I encountered yesterday while building up another older Campy rear hub. The text is upside down when standing over (or behind) the bike.

Have any of you encountered something similar? Could this have been a factory oops? What say you fellow wheel builders???

The anomalous hub also has a freshly-machined profile visible where the tube meets the flange, whereas on the other hub the tube meets the flange with a more gradual radius profile. Has this been re-welded?

No, never seen such a monstrosity. I don't think that hub is ridable. 
Have you considered a left-side drive train?
