I would be more than happy to add further information to my web site
regarding Estey player pipe organ rolls.  The current information is
a result of my compilation of the list of rolls from several sources,
including one of the bound volume of roll listings from the Frank L.
Chipman organ in Pennsylvania, as well as my own collection of rolls.

Over the years I've received requests for further information about
the operation of the rolls.  If anyone on this list has detailed
information, please send it to me and I'll be glad to post it for
everyone to read.
