I have a Concert Roller Organ that uses rollers that are 6-3/8 inches
long and about 1-1/2 inches diameter.  I only have about four (4) for
this organ.  I also have a "Orchestrone" Monroe Organ Co. 14-key organ
that uses rolls that are 2-5/8 inches wide.  I only have one (1) roll
for this organ

Does anyone know if there are replicas or even originals available for
these organs?

Thanks,
Charles E. Schubert
