Hi Mary and welcome to WAGSland. A lot of makers did not put their name on their skillets and other cookware but they did have, at times, other markings such as catalog numbers, pattern makers marks, molder's marks, etc. I would guess that the 8 on the bottom of your pan is most likely the pans size (a No.8 which would measure about 10 to 10-1/2" diameter. The B could be anything like a pattern mark, etc. Your pan may have been made by one of any number of patterns the company had and it happened to be the "B" pattern. Such numbers are insignificant. A photo if you can post one might help identify your pan's maker but that's not very likely. Hope this helps some.
