Can anyone help with this one? (vase)

It is part of a group of 6 and is wafer thin with a very good ring to it.
They stand at 11.5cm 4.75" tall.
I do not know what age they are or who they re made by so any help will be appreciated.
Thank you.

Oh, I had a set of these without the decoration at the top - I never found the maker, but they're wonderful quality. I suspected John Walsh Walsh as a possibility.

I found, though, that they don't take kindly to ice cubes... the bottom fell off one of the glasses. Another perished whilst I stirred a cocktail in it perhaps a touch too vigorously with a long spoon. Oops.

I tend to stick to chunky glasses now.

Cheer Nic, I would not risk using these as they are incredibly thin and knowing my luck...
