I only have one of these stems.  Likely a claret or some such purpose.   I think my partner bought it for me.  If so, it was cheap!  Kind of a miracle as I had always thought he paid no attention to the bazillions of glasses that fill all corners of our house!  I’ve played around with the colour and contrast of the photos in order to show the detail of the etch.  Very intricate.  The cross thatching (for lack of a better word) reminds me of that of Fostoria’s Melrose, but it is not Melrose.  I also like the stem.
