Mike, I think they made the 3, 5, and 8 with deep hammering. The 40-41 Sears catalog shows these deep hammered pans as being "Best Made" (triple ground) and "Merit" (double ground and not as fine grained as Best Made). Listed for Best Made are 5, 8, and 10 skillets and covers for the two larger sizes. And, for Merit, they show 3, 5, 8, and 10 with covers for the two larger sizes. I don't know if the Merit grade is the deeply or not so deeply hammered pans. Someone here said the 3 was made in the deep hammered size. Also No.8 chicken fryers and dutch ovens in Best Made and Merit grades. Maybe someone else can fill in some more sizes. When heat treated in an oven to 450 deg. these pans take on a very nice dark color. A set would be great looking. I don't know if these pans were also sold through other outlets than at Sears or if they were a contract item from Sears only.
