"Band organs seem to have been made at many pitches other than the "C"
centered tuning."  This is _speculation_.  The higher pitches would be
slightly less expensive to produce because of materials, especially in
the bass pipes.  Also, a higher pitched instrument will sound
"brighter", and that would be another reason for a higher pitch.  Other
than that, maybe the new owners wife could only sing in E-flat! (jokes!)

I'm sure they were marked the way they were to avoid confusion during
factory assembly.

Have a Happy Easter, Everybody

 [ Well, a W165 roll sounds in C when played on a big Style 165 organ,
 [ but the same roll sounds in E-flat on the smaller Style 157.  How
 [ are the pipes marked, and how can this transposing be explained?
