While it is true that the 20-note tracker bar of Wilcox and White is
in simple ascending order of pitch, the arrangement of reeds in their
cells may not be.

In my Symphonia, the tracker bar runs front to back, as the rolls play
from left to right, but the reeds are arrayed along the front, like
piano keys.  Since some sort of tubing was needed to turn the corner,
the builder took the liberty of arranging the reeds in pitch order, but
alternating from the left and right sides, working from the outside in,
just like many pipe organ chests.

Since this organ has been restored, this sequence may not be original.
To add to the confusion, someone wrote the reed pitches over the cells,
but in linear order, and transposed a fourth.  I wonder if I even have
the original reeds?  The instrument sounds beautiful.
