I saw those figures and documentations. All out of Helmholtz,
"Sensations of Tone". ( the translator Ellis's appendex) Then based
on Ellis's measurements of 7 tunings by a method that is not
described, the tuning plans are  hypothesized by Jorgensen.  All of
this prove his contention that tuners of that time were "tuning a
well temperament and then calling it equal temperament".(p.545)   It
is far more accurate to say that tuners were trying to tune ET, but
not achieving it to the standards of today.  Jorgensen does present
credible evidence that other tuning schemes particularly meantone
were also used. 
	It is a mistake to assume the bearing plans given are the ones that
were actually used. They are only Jorgensen's educated guesses taken
from data gathered by Ellis outside the factory. No authentic tuning
schemes, or instructions from the factory on how to tune the
Broadwood piano are given. Again like Bach's comments on the tuning
of WTC, this is information that may not exist today.
