Pendalum sliders

[fartwell2000]

Does anyone know of any modern bell hanging jobs where pendalum 
sliders have been fitted?
I am aware that the six hung by Matt Higby at Warden Hill have them.
I have only ever seen a couple of bells fitted with them-S Andrew 
Ramsbottom,Lancs(one ringing bell and four seperate clock bells),and 
if my memory serves me correctly,on the unringable three at St 
Peter,Stainforth,N Yorks.
