[Bell Historians] Warners retuning during augmentations

[Richard Smith]

Is anyone aware of any examples of a John Warner 
augmentation by topping and tailing, or just adding a tenor, 
where they tuned the n-2 of the original ring down a 
semitone rather than recasting it?

(For example, the bells in a major six in G would have notes 
G A B C D E.  Topping and tailing to make an eight would add 
Fs at both ends, but the 4 of the original six needs moving 
from B to Bb.  In my experience this was normally done by 
casting a new bell.)
