If you are asking about the Wurlitzer SA that is currently for sale
on the web then as a nickelodeon piano it uses 10-tune Wurlitzer
Style APP music rolls.  The APP roll was the workhorse of Wurlitzer
and came as five-tune rolls and ten-tune rolls most commonly.  All
kinds of music can be found on those rolls.

At some time in the early 'twenties the Wurlitzer Company started
using QRS masters for their arranging department.  Earlier rolls were
all done by Wurlitzer by their staff arrangers.  Some of these are
really good.  There is no set time for the change as they would use
some of their early arrangements as well a QRS arrangements on the
same multi-tune roll.  The unfortunate part is that currently no one
is re-cutting Wurlitzer APP rolls to my knowledge.
