Thanks Pip, David (Vidfletch) suggested on the Whitefriars board that I check out the capacity, which is around 4fl.
I then discovered that 4 fl oz = roughly 110 ml. A standard pub white wine measure is 125 ml, so these must be sherry glasses.
Now another thing, the stem on one of the 6 is much much wider than the others...the height of the stem, and of the bowl is exact to the others, so I would expect that to be a proper set. But is the stem variation a normal thing? I presume the bowl is mould blown and the rest freeblown?
You can see the gallery of the set
here:
The thick one is at the front, far left.
Thanks
