The outside of the master cylinder that cup came from was immaculate, so I'm inclined to believe it never saw any use.  Thankfully, that rotten cup was the only bad part.  I wish the rest of my brake system had such smooth cylinder bores (but I honed them and they haven't leaked yet -- fingers crossed).  Locating front wheel cylinders for the early cars isn't so easy these days, so if mine start leaking in the future, I may have to get them sleeved.

Doh!  Of course.
