Tuning forks

B, which makes the 11th C# however you look at it. In turn,
this makes Evesham C# as the tenor was modelled on
Worcester 11th..."

The bells I previously mentioned were all tuned by forks
and are superb examples of tuning at its best.  Evesham
were also tuned with forks alone and perhaps David can
confirm Evesham were tuned by Paul Taylor.  A modern
C-sharp ring does not have the magic of Evesham. 
Personally I prefer the sound of a D-flat ring like Truro. 
However there is a prospect of a new C-sharp twelve coming
up and we must wait and see how they turn out.Personally if
I was paying for them I would prefer them to be in the key
of D-flat and tuned by forks rather than a guy just gazing
at the dial of a machine! 
Is there a book on bell tuning through the ages as I often
wonder how the incomparable Bow ten of Lester and Pack of
1762 with its superb sounding tenor of 1738 were tuned and
who tuned them.  There have been many subtle changes of
profile and tuning over the past 270 years or so and it
would be interesting for all this information to come
together in a book available to the general public.
