Organ Pipe Scales and Design
By Leonardo Perretti
A nice book on the subject was written by Christhard Mahrenholz:
'The calculation of organ pipe scales from the middle ages to the
mid-nineteenth century' (this is the title of the English version).
You can find it at: http://www.ndirect.co.uk/~amen/books.html
A lot of tables and explanations can be found in the famous treatise
'L'art du facteur d'orgue' by Dom Bedos des Celles. In the same
treatise there is a very fine description of how pipes can be built.
I have only the French and Italian versions; surely an English
translation is available somewhere.
Another font is the ponderous treatise by Toepfer, written in Germany
about the end of last century. This treatise is considered the place
where the measures of the pipes have been standardized; the features of
such standardization are those reported in Audsley. I have not the
book at hand so I cannot give more information.
[ I've seen an English translation of this book; it's very good.

As far as I know, there is no general treatise where the features of
the pipes belonging to automatic instruments are described; it would be
nice if some wizard of automatic organs would decide to write it !!
Hope this helps.
Best regards to all
