With all the recent Reproduco talk it jogged a few brain cells and 
I remembered when I bought some items from Harvey Roehl's estate that
there was an old Reproduco piece included.  It is titled "Instructions
and List of Parts, Reproduco Organs".  It is a 8-page item.  

It includes neat things like tracker bar layouts (3), and what appears
to be a drawing and parts list for the coin magazine.  If this was not
reproduced by Vestal or anyone else,  does anyone need a copy of it?
Perhaps there is enough interest to have it professionally copied.
