Amateur orgain building

Instructions first published in 1887 on how to make an organ (the type you listen to, not sweetbreads, the kind some people eat. )
Most of the parts are made from wood, but there is a section that shows how to make paper organ pipes (starting on page 15).
I suspect other parts could be made from foam core or lacquered thick cardboard instead of wood, to make desktop organ like this

or cut up some wood, snip some wire and make something a bit more ambitious

The links lead to scanned copies from two different books.
The book is available as a reprint for about 30 Dollars.
