Assuming there is an actual roll-playing organ which you can buy,
be assured that virtually all 110 mm wide 20-note rolls will play
on the organ.  (After about 1995 virtually all Hofbauer 20-ers used
electronic cartridges, not rolls.)

I would recommend looking at Melvyn Wright's offerings at
http://www.melright.com/busker  He offers good service, prices, and
selection.  There is a lot of good music available through others,
as well.

The spools are a different matter.  Hofbauer used its own spool design,
and stopped producing them.  It is not particularly difficult to adapt
the Raffin style spool, but it must be done with precision if the roll
is to play properly.

Start here for self-service information if you can't find a friend who
knows how to fix it:
