I am surprised you have not read the book, which is one of the few 
classics available.  Have you not read Junghans in 'Der Piano- und 
FlŸgelbau' either, which details a scale on very similar principles 
to Wolfenden's; not that several makers were not already following 
these principles -- there was nothing new about it in 1916 -- and 
most still do.  In fact an 1865 Kirkman I am currently working on 
might almost have been the model for such a scale.

What scales have you designed and what principles did you follow?
