I have four Bohemian cut to clear crystal wine glasses, each a different color. Each also has etched onto the base a stemware mark that I have not been able to identify. Does anyone recognize this mark? If so, I would very much appreciate knowing more about it.
Possibly Beyer & Company, Neustadt/Waldnaab, Germany active 20th century, producing drinkware. My reference shows a different shape for the shield, but may be worth investigating.
