No, it's Sklo Union. It's somewhere on the database that goes with Sklo Union Art Before Industry, Marcus Newhall. I don't have the time to look it up for you though. Crown Crystal made a lookalike pattern as well (just for the record).
Edited to add: Actually, better correct that. It's probably Sklo Union, but there are so many variations of these around that there could have been many other manufacturers who copied, as well as Crown.
