Only 2-3 of these pieces are known. I bought one about 10 years ago off of eBay for about $4800. Doug McGillvary owned a second one that he bought from Dick Macky in September of 1996. When I bought Doug's threadless porcelain insulator collection, I ended up with a second one of these so am finally selling it. Great, distinctive Bennington brown and yellow glaze. Asking $7500 which includes shipping, insurance, and delivery confirmation. 1/4" glaze flake on the center edge. 3/8" x 1/8" shallow bottom chip that shows red pottery. 5/8" x 3/16" shallow chip on bottom which also shows red pottery.
