I am starting to collect as much information as possible about player
pipe organs.  Specifically, I am interested in Aeolian products.
I would like to purchase roll catalogs for both the Aeolian 116 note
rolls and the Duo-Art organ rolls. Additionally, I would like any
technical information on the Concertola player unit.  Schematics and
service manuals would be at the top of my interest list.  Almost any
information concerning these instruments would be appreciated.
