Just a bump from 2008,
and ive had another look, its quite likely its a continental 71 (crossed 7) than vt

I know its a long shot, any idea of a good Continental Crystal maker for this one ?
its very finely done, could be earlier than my earlier guess.
Cheers
Andy
A quote from Bernard on this thread
http://www.glassmessages.com/index.php/topic,19505.0.html'Kristi — In my experience, British tie number "1"s are either a single vertical, or a single vertical on a horizontal base like the first two strokes in a game of hangman; "7"s are as printed here.
Continental "1"s have a long, downward pointing curved serif, so that the figure looks like a tent just about to topple over in a strong wind from the left; "7"s have a horizontal cross bar in the middle.
On their own English "7"s and Continental "1"s can be quite similar'
Not sure why i didnt notice the coincidence with the 71 on this one
