The Concertola cabinet is to the right of the piano.  A small control box
under the owner's hand has buttons to select different songs.

Hello Bob,   A few months ago Terry Smythe kindly sent me a set of photocopied diagrams for the piano Concertola.  To me this was a most important find as I'd been looking for that information for over 30 years.  (Obviously I did not treat it as a full-time job.)

I have sent JPEG image scans of the electrical system and trust that they can be posted to the MMD Archives.  There are also pneumatic and layout drawings which I can send along later as well if there is interest.

These diagrams are fuzzy but the information is there.  Because they are fuzzy I have had to scan them at a high resolution so you can extract as much as possible from them.  This means that they are a sizeable download.

Hope this solves your problem.
