Thank you folks and for the ID Mike. Thats great to know.
There is what looks to be a flint version in the Glass Gallery (File 1463-66) "Rd.No. 99715, registered 9th May 1888." The registration number is now pretty obvious when I now take another look at it - doh!
In the XV(1895) Pattern Book it appears to have been made in two sizes 7 1/2 and 9 1/2.
Message to t'other Anne - Please feel free to add an image of my green version the the Glass Gallery.
