Not as I understand what you, Dick S., and David A. have been saying. I
suspect they're all the same, at least the first two are the same.
Certainly NY Central is no longer shipped anything marked Crane's
Parchment, or Parchmont either...

 I saw the swatchbook, it said "Cover stock."
But what about the "brightener"?  Is that the stuff fluoresces?  Doesn't
that wear off in a year or two? 
I was also told that brighteners in paper wash out in the processing, in
the wash water if not sooner, but have never tested it...
