 Thank you, that was very quick.
I've looked up the RW ref - it's from a week after week article  '
First Performances'  by  Frank Blagrove,  but it doesn't give the PN
I suppose that he got it and details from some Association Peal Book.
I'm trying to understand glide symmetry which I thought was very well
explained in your website but RAS's response has me very puzzled... I
respect his opinions but why is it that when he asks: "Can you think
of any methods that were called 'Double' but that did not have glide
symmetry, then?  I'm not aware of any."
Actually I can find no examples of glide symmetry in 18th cent books
at all, but I have found both palindromic  & non-palindromic methods
each with 'double' in their title
