THAT SAID, I am not sure I ever had a 694.
One of my faves was the 253 Warwickshire, as I only ever saw one... Ever... And I have it tucked away somewhere.
Another favourite is a Victorian half pint from... Somewhere in the east end of London anyway.
Strangely, the rarest ones I have found to be are the Scottish ones, Cornish and Welsh, with me never actually finding any from Cornwall.
Somerset, Dorset, Bath and Avon, yes, but nothing west of Saltash...
I no longer collect, so things might have changed.
