I've check the #8, and #9 lids, on there respective deep skillets, and I will have to say, no. They do not fit. The taper on the deep skillet makes it too wide at the top for the lid. I even tried a #9 lid, on the #8, with no luck. ON the earliest series 1 thru 4 ERIE skillets, the lids fit but they are loose. They do fit the later 5 thru 6 series skillets much better. At least these are my findings. The catalog that Perry was so kind to have reprinted, does not show lids for either the regular, or the deep skillets.
