Hi all,i immediately recognised this as a shape I'd seen before drooling over pictures of old glass and when i got it into my hands i was pleased to find it had a rough broken pontil,but it's very light with a hollow stopper and doesn't seem to have a ring to it,that maybe the shape,it does have bubbles and bits though with wear to the base,23cm to top of stopper,many thanks Ant..
PSit has a sort of frosty leaf decoration.
