I am pretty sure that John has catalogues with IM and other "off" brands of Griswold. I not only collect it, but John collects it too.

Will, I was just going by the Blue Book. There is a Griswold shipping order from 1931 that shows unmarked DO's in sizes 7,8,9,10 and also states trivets are available for them as well. But, things change, or it could have stayed that way. My point is that the 1931 shipping order shows one thing, but as we can see from Griswolds catalogs, items are added. Case in point is Griswolds 1890-91 catalog shows DO's in sizes 8,9, and 10, the Circa 1904 catalog shows them in sizes 8,9,10,11, the Circa 1910 shows them in sizes 6,7,8,9,10,11, the Griswold 1918 catalog shows them in sizes 6,7,8,9,10,11,12, and 13, and the Griswold 1940-1941 shows them in sizes 6,7,8,9,10,11,12, and 13. So when they were making the unmarked IM 7,8,9, and 10 DO's in 1931, they were also making DO's in sizes 11,12, and 13. Its just something I'm pointing out. I think it is possible they made unmarked DO's in sizes larger than 10 but I certainly don't have any proof of it.
