Hi David,
Sure. This evening I'll try and rig up a proper photo for you, no problem at all... other than the quality of my camera!
BTW, I distinctly remember my aunt having these same Calypto sherry glasses back in the 1970s. It's probably not relevant, but the family lived in St Helens and her father (my maternal grandfather) was a Pilkington employee.
She's on my list of people to call, so I'll see if she remembers where they came from!
