Hi Frank, Sorry, couldn't get organised to post more photos yesterday, but I have some now. I tend to be a bit mean with photos, forgetting it's not Ebay and I won't get charged for more than one!
In answer to your question, I hadn't noticed before but, the stopper is blown. The handle is also cut quite beautifully with three what you might call diamond cuts on the outside, so it catches the light really well, although maybe not so brilliantly in my photo since it's a very dull day.
Regards, Iain
