That's sure possible Jim. Sears did the same thing in contracting with Griswold, Favorite, Wagner and maybe others to make their cookware. Note that the Griswold Puritan and Merit skillets have unusual handles.
Has anyone compared very closely the skillet bowl details, profiles, and size with marked Favorite and CHF skillets? If the bowl sizes are different I would see a good possibility that the skillets were made by someone other than Favorite or CHF and may have been copied from them. When I look at all the different handles and skillet bottoms/heat rims I don't really see "Favorite" although it could be.
