Thanks Gadget, aelfric and despair,
'Abbey...' does seems the attractive and obvious 'bb' answer to the word puzzle. As Karen McDonald has so clearly shown an issue with the serifs (my term) to the bs, the superscript and the subscript is outstanding. Her interpretation of overwriting had not been refuted nor the super and sub-scripts explained.
I am again stumped. Any further thoughts are more than welcome.
