Hi All, Just a short note to let you know that the player action
in the Schiller upright player piano was positively identified by
Alan H. Mueller. He sent me some advertisements from Schiller that
included a diagram of their 'Schiller Ideal Pneumatic System' action.
Further research turned up a few patents, but none of them relate
directly to the stack. I have started a webpage about the action;
it's at https://www.player-care.com/system97.html
('97'; that's how many player systems have been identified since I
started maintaining the Player Piano Makers webpage about 17 years ago.
When I created the webpage, there were about 60 player actions whose
makers had been identified.)
