Googling "65 note player piano rolls" will bring up a few sources for
65-note rolls.  I was able to acquire a 65-note test roll from a source
in the UK who responded to a request I posted here.  You will have to
double-tube the notes 66 through 82 (C5 to C8, etc.) tc.,to make the
music sound right.
While you can double-tube up to 88, anything above 82 is unnecessary.

The 65-note rolls have pinned ends and 88-note rolls are recessed.  The
65-note spool box will have to be modified to accommodate the 88-note
rolls.  You will also have to adapt/modify the roll tracker, as the 88-
note rolls are about 1/8 inch shorter.
