Hi and welcome to the gmb!
I can't get your image to enlarge to see it in any detail - but it is not Whitefriars.
There is a whole load of techie help available here;
http://www.glassmessages.com/index.php/board,22.0.htmlto help you!
We like clear, in-focus images of the whole piece, the base (we
really like looking at bottoms here, they contain a wealth of information ) and the rim finish - and of any markings which are on it.
We like them to be against a plain white background so we can see the glass clearly. (some A4 paper will do).
Looking forward to seeing this beast in all its glory!
