If it was a bad lobe, I don't know that the distributor machine would have caught that.....

Also when it was being rebuilt it most likely would have been found.

Yes it would. You look around the whole dial and you can see the spark events of each lobe.
If one lobe is worn it would show a late spark on that lobe.
