thanks - I'd have thought unlikely that Reynolds was wrong in his comments regarding the commencement dates of the back stamps, though as with all such factory marks there is the possibility of a leeway of a year or two, but not back to c. 1910. Looks like fruiting vine was popular and had quite a long life span, like some other of their patterns. Walsh was a high end production and it's a shame we can't find the stuff as commonly as we see T/Webb, Edinburgh, or Stuart. Agree with you re the similarity of A4197 to fruiting vine, but there appears not to be a pattern name in the pattern book for that particular glass - unless I've missed it - as it is I had to use a lens to see the wording - am I reading the word butterfly?, and some of the wording is impossible to decipher, but there's no doubting the almost identical appearance. Fruiting vine is more attractive I think than Kenilworth, of which I have two or three, and which appears more staid and less arty.
