I too would sure like to hear if Aeolian made their ten-roll Concertola
for anything beyond the Duo-Art rolls for the organs and the piano
version for that use.  Not once have I ever heard or read of the
116-note organ rolls or the 58-note rolls being used in any multi-roll
Concertola.  I seriously doubt that either one existed.

People sometimes refer to the single roll stand-alone [remote] organ
roll player as a Concertola.  Could this be the source of confusion?
