The growing O-Rollography has been expanded to 710 rolls now and
the links to it have been fixed. You can find it at

  http://www.rickcrandall.net/article80.php 

Recent new additions have been with the welcomed recent contributions
by John Gourley, Glen Grabinsky, John Rutosky, Brad McClincy and Don
Teach.  If you have any O-roll tune info not yet catalogued, please
contact me or send to me at Rick@AspenVenture.com

I now have a document explaining the roll-numbering confusions that
I'll send you if you email me -- and it will be included in the next
posting in about a month or so, depending on new submissions.  However
I'll note it here:

  If you see QRS, Clark, Columbia, Capitol or National, the roll is
  original.  If you see Automatic or composite, the roll is a recut
  and likely not the original tune list for that roll number.
