Bohemian Glass amethyst ashtray

This bowl/ashtray is 7.5" in diameter and 3.75" high. The bottom is flat ground and polished, but has very slight age related wear. It has a silver "Bohemian Glass" label. It is a heavy bowl, weighing in at 4 lbs 4 ounces. It has similarities to the Hineri bowl that I posted a few weeks ago. Not sure of the maker. Opinions range from Skrdlovice to Chribska among them as has opinions. I do not know who made it, but welcome any thoughts.
