II
only the 8 largest Taylor bells: D1, F1 --- B1
Notice the A1-bell clearly deviating from the general pattern.
This bell cracked in 2000, after having been retuned (up) by Eijsbouts
in 1991.
Eijsbouts welded the bell in 2002, after which operation it turned
out its tuning
had changed relatively radically. It was tuned again after that.
Besides significant tuning problems occuring, as a result of all
of these operations
this bell has lost many of the principal sound characteristics
that are
typical for Taylor bells of 1930.

internal tuning quint partials of the 18 largest Taylor bells.
The stronly deviating tuning of the quint of the A1-bell is principally
the result
of the attempt in 1991 by Eijsbouts to raise the general pitch
of this bell.
Obviously that didn't work for this quint.
