MMDer J. B. Roth has a quantity of piano roll graph paper he wishes
to sell.  He writes:

  "This is my piano roll graph paper.  It's configured for 88-note
  players.  It's 11-1/4 inches wide.  It has indications for treble
  and bass Themodist (snake bite) holes, and sustainer pedal as well.
  The note holes are nine-to-the-inch (across) and 1/8-inch apart
  (lengthwise) for sure repetition with trills."

It's perhaps slightly heavier than the piano roll paper used nowadays
by QRS and others, and it cuts very nicely with a sharp blade.  The
printing is very precise.

Price is $4.50 for 30 feet of paper, or $12.00 for 100 feet, without
spool, plus a modest shipping and handling charge.  For more
information contact J. B. Roth <sovrenty@earthlink.net>.
