Are you sure the Kilgen rolls were 88-note?  I have a Kilgen with a
quad (4 tracker bar) player.  The tracker bars are 98 notes, though
spaced like 88-note piano rolls.  The 5 holes at each end are
elongated.  The rolls were Clarke (Rossler/Hunholz) Organ rolls, I
think type XC, though all Clarke organ rolls used the same tracker bar.
I only have 3/4 of one roll for my player.

Would you consider parting with (some of) them?
