Charlee & Jeff nice to hear in from you 2 on this subject. :) So far I have had in Griswold a #1, #3, couple of #5, #9, NES #11, #18, couple #22, #32, & a 273. I have also had in G.F. FILLEY #12 & #5. Every place I go antique store, flea market, & auction I am always looking for a new one to add to my collection. Jeff as to cooking in them I must confess I do not I like them for their looks not their fuction. I do use my skillets,griddles, & dutch ovens though I hope that counts. ;D ;D ;D If you don't mind could you take a pic of your muffin pans I sure would like to see them and everyone who reads this sure will. Do you or anyone else know how many G.F. Filley muffin pan sizes and kinds there are I sure would like to know just in case I do get them all which is a goal of mine that and the Griswold ones I think they will keep me busy finding for a long while.
