There is a Wurlitzer Model I Nickelodeon on eBay that has an automatic
roll changer which holds 5 rolls at a time.

Does it actually thread the roll on to the takeup spool and in the
process unthread and roll up the previous roll all auto-magically,
or is this just a way to basically store 5 rolls in the piano and each
one would have to be set up by hand?

Just wondering...
