Well took a ride today to look for some cast iron (Griswold)newbie. first stop -o- second stop I picked up 3,1 #8 block letter Gris with heat ring needs cleaning,2 a#12 Wagner Sidney o and last ??? a #9 Erie that I do not know if fake or not, it's pretty caked up and hard to read. The ones on e-bay seem to have straight sides to the heat ring this ones is curved to the heat ring but smooth like glass on the inside.it has the EIRE on top and #9 at 6 o'clock Any thoughts.
