Boyd Glass (USA) owns a mold which has the same number of horizontal rows (10) on the base, but the bees have different placement, and the finial on the lid is different, as is the location of the bees on the outside of the base. It is contemporary and has been made in numerous colors. I don't know who made your version, nor do I know where Boyd got their mold. In the little book they released, it only mentions that they acquired a bunch of molds from Imperial at one time. I also cross-checked my Degenhart book (the Boyd factory is the same as the Degenhart factory, just new owners) and it was not in that book, so the mold was new to Boyd and not inherited when the factory was purchased from Mrs. Degenhart. While this does not tell you who made it, it also eliminates one of the 'possible contenders'.
