I accidentally broke a vintage whiskey glass that I got from a friend's father when he passed away. I've been looking for a replacement in a similar style, but haven't been able to find anything suitable. The bottom of the glass was cut in a particular way, similar to what's found in this link, though not quite the same. What I had was much more intricate, and there were four major protrusions from the bottom.
Does anyone have an idea of what this bottom cut style is called? Most whiskey glasses I find when I search online just have a round bottom.
EDIT: For some extra info, the etchings on the side of the glass I had were similar to those found in this ebay listing. If anyone has information on who made these glasses or what kind of etchings they are, this may help.
