If this instrument was built for Philipps PM and CP rolls, which
were also made by Wurlitzer, it would be a shame to change the scale.
This would also require major changes to the tracker bar and roll box
as the PM rolls are narrower than others.

May I suggest that the owners purchase new PM rolls.  These are made
by Thomas Jansen of Germany and are copies of the excellent original
Philipps arrangements.  Play-Rite copies of original Wurlitzer PM and
CP rolls, made around 30 years ago, are usually available.  I recently
bought a very large batch for my Pianella.
