Chicago Hardward Foundry in Chicago bought some of the assets of the bankrupt Favorite Stove & Range Co. in Piqua, OH in 1933 or 34. At least they got some of Favorite's patterns and seem to have used them to make more "Favorite" cookware in Chicago under their own name. Different company, different foundry, similiar pieces but with a name change or slight modifications. CHF pieces are a little uncommon but not all that hard to find a few of. I don't think they have any great value other than being good users as they are nicely cast and styled pans. Up to you if you want to destroy a piece of historical artwork or cook in the pan.
