Thanks for your reply David , it hadn’t crossed my mind that it could be a firing glass but now you mention it perhaps it maybe ?.You spurned me on to have a look through a few books I’ve got and I see what you mean about the foot ,some do have a very similar look about them .In A Wine Lover’s Glasses the AC Hubbard,Jr Collection,there is even one with a bowl a bit like mine although that one has a colour twist stem.What I can’t find is a glass as tiny as mine ,which is 2.5 “ high ,the smallest ones I’ve come across are just under 4”.I would guess with such a small glass the maker wouldn’t bother with a stem one could date it by easily ?
