Have not cleaned it yet but I think the large one is a Lodge. Saw a photo of one like it with a Lodge logo.It has the 4 little nub feet. Measures 19 1/2 x 11 1/2 not counting handles. A Lodge #7 flat bottom, BSR dry fry griddle 19 x 11 not counting handles. I think the BSR griddle has the smoothest cooking surface I have seen on a long griddle. The #3 skillet is for size comparison.
