I'm trying to ID the maker for this skillet griddle. It's marked on the bottom in block letters "11 1/4 INCH SKILLET GRIDDLE" in the lower third of the pan. There's a "B" just about where the handle meets the pan, and on the underside of the handle itself. The pan is machined smooth on the cooking surface; the underside is less smooth, but still fine grained. It's weighty - about 4-1/4 pounds.
Any experts out there know this one?
