Ok, after discussion and further searching, I'm not really disagreeing it's possibly English but more that I can't see how it can definitely be identified as Thomas Webb

There are definite gilding lines around all the padded work if you enlarge this photo in my link below. However, that could have happened because the gilding of the padding has gone all on to the glass area surrounding the padding, making it look like an outline. But there is a lot of it so to me it looked like an outline on all the design.
http://www.glassmessages.com/index.php?action=dlattach;topic=60408.0;attach=177115;imageThat is very different to how my vases from Jules Barbe look. And the other work I have seen by him. They are incredibly precise and the gilding does not go over the edge of the padding. I accept that there may have been other gilders in the factory if indeed it was made by Thomas Webb, however I would still query that technique of execution.
Just another aside re the number of gilders. Firstly,a correction to my post on dates, where CH says that Jules Barbe finished at TW in 1901 not 1902 (the date I calculated from the article). Secondly, it does also say in the book ,page 326
'... Apart from the information that a relative, Paul Tallandier, went to work as an enameller for Coalport, the histories of the other craftsmen are not known. Barbe and his son settled at No. 7 Collis Street, and went to work at Thomas Webb and Sons.'
I interpret that info that both Barbe and his son went to work at Thomas Webb. (M. J. Barbe is cited as being there 1879-1901).
That period appears to cover the time this piece was made, gilded and a silver collar attached. Barbe was a master artist who trained in Paris as a decorative artist '...at a time when the 'Union Centrale des Arts Decoratifs' was established to support those arts.'
I suppose the question is how many were working at Thomas Webb as gilders? If there were 'many' then yes I suppose I buy that the quality of the work might vary. If there were only Jules Barbe and his son and the odd other person, then I 'm musing there would have been high quality control on enamel and gilt work emanating from the factory.
With regard to how many workers in this field would be at a particular factory, there is an interesting comment in the Crystal Years (R.S. Williams-Thomas), the book written about Stevens and Williams. On page 49 he says:
'
The works had been completely rebuilt in 1870, a bare quarter of a mile from the 1776 original Moor Lane factory. This gave a chance to build in a hollow square with the glasshouse in the open centre. The gilding shop was in one corner of the square and was a little, dark, one-storey shed, with it's muffle sited in an off-shoot passage leading to the blacksmith's shop next door. There was scant room for three artists, all of whom needed to face the pale light from the reeded windowHe goes on to talk about another three artists specifically named who worked at S&W. i.e. I just do not get the impression that there were hundreds or even 'many' people carrying out this work at a glassworks.
So I'm circumspect about the Thomas Webb identification a bit. Also I can't seem to find any bright blue satin glass cased over white pieces that have been definitely identified as Thomas Webb. Nor can I find that particular design on something definitely id'd as Thomas Webb. Can't find a primary source.
I can see the design on your vase (pine needles) on the peachblow vase on page 316 of CH British Glass 180-1914 .
