The fish was ??????? big....

I came across this HUGE crystal pedestal bowl while buying several pieces of crystal/cut glass from an Orlando area estate. The collector was into EVERYTHING. He had the resources to buy and a 10,000 sf home to display whatever his heart desired. It was one of the most diverse and impressive collections of high end hand crafted items I've ever seen. So, as I'm unpacking my treasures and beginning the process of researching manufacturers, patterns etc, I've already hit a wall with this monster bowl. I've only found 1 bowl similar to this online and my eyes are already beginning to cross. If anyone has any insight about the manufacturer...I would greatly appreciate anything sent my way. Only about 65-70 pieces to go after this one! What have I gotten myself in to, AGAIN?? LOL
The piece is 17" tall and the top diameter is 13"
