Large steel bells

[Alan J.Birney]

I was wondering if anyone has seen the 70cwt steel bell by Vickers 
that is/or was hung at the Italian church,Hatton Garden,London.
I am particularly interested in how it is/was hung, and wether or not 
it is/was of good tone.
Also where is the largest existing steel bell located in the British 
Isles, and how many steel bells of 20cwt or over still exist in the 
U.K.
Thanks
Alan
