I am interested in finding any information about Estey Pipe Organs and
the self-registering roll player they made during the '20s.  I believe
that they were well made and innovative organs, and the roll player
looks reasonable (I can only find a tracker hole definition).  Did they
play well, or have problems?  Will they play the 116 note organ rolls?
Have the rolls been recut? Where can you find rolls?
