In 1975 I obtained some blueprints that were of limited help from Bill Wherry who, most unfortunately, died a few years ago. I also have Xerox copies of pages from the AMICA Bulletin at around the same time which are much clearer reduced copies of the same diagrams. The only print that is not reproduced is a mangled one of the organ Concertola which bears only a limited passing resemblance to the piano version and is virtually useless as a result.
There are also a few articles on the late Duo-Art that are scattered through early AMICA journals that might be of help. February, 1974 and mid-1984 issues are an example. I was not a member of AMICA at the time and so can't be more exact. I expect that these articles may appear in "Technicalities."
During the restoration I, too, made up a few diagrams, but there is still some mystery about the function of some of the elaborate pneumatic controls which, since they continue to work, remain "little black boxes."
Contact me at james_heyworth@sunshine.net if you think there is any information we can share. I also believe that Larry Norman is/was working on a Concertola two or three years ago. He may be able to help.
At present I am still _thinking_ about MIDIfying the interface to save wear and tear on the Concertola itself. Although I think it should not be difficult to do, the thought process has been going on for some time...
