The recent thread regarding band organ tuning stability brought to mind
a related inquiry.  I recently acquired a 56er Wilhelm Bruder book
operated organ.  Included with the organ was a small book which plays
all notes of the scale in sequence, and then plays various octaves and
intervals.  I assume this book is used for tuning purposes.  Am I
correct in this assumption?

Is there any book or publication available which covers the procedures
for tuning a band organ?  Comments from our band organ technicians
would be appreciated.
