Oldest Bells

[mikechester_uk]

An old chestnut, I know.

But, on a long journey back from ringing in Wales, Bill H - 
Llanfeugan are a "Premier League" ring of 8, Taylors 1921(?) if 
memory serves me right, record them just in case - superb! 

What is

a) the oldest bell in a ringing peal

b) the oldest ring - Smithfield was the one that came to mind

c) the oldest ringable ring on contemporary fittings

Any offers?

Let's start with Ashow for c) early C18 - though the wheels look 
younger admittedly
