Jeff Katchko and Ken Willick dug up this piece... It's an awesome CD 365 "No 331" in bubbly clear! Part of the No 331 embossing is visible, but there is enough of the skirt that is intact to say that this piece was NOT also embossed BROOKFIELD.
This is the first time that any of the cemented multipart Brookfield power pieces shown in the 1912 Brookfield catalog have been found. They have all been assigned CD numbers, but of course they are only listed in the price guide when actual specimens have been found. The catalog gives the dimensions of this piece as 8 1/2 " x 7 1/4" rated for a line voltage of 25,000 volts and weighing 7 pounds. Code word "Rabid".
This is an experimental glass formula, and it filled with micro bubbles, giving it this appearance. The odd patch on the right on the upper umbrella, is a repair.
It was amazing to see this piece in person. While it was shown at the National, I was able to see it at the YPCIC swap, along with some other [id=163078115; one of a kind porcelain pieces] that were also recently found.
