My assumption the lid is also a copy (we know the pot is) is based on a couple of other things. Wapak may have been good about covering names on the pieces they copied, but they weren't necessarily that fastidious about changing/filling in other marks like size and pattern numbers. The lid in the photo looks like it fits rather well. Since the pot, being a copy made using an actual pan as a pattern (or the basis of one), would have to be smaller than the pot it copied (due to iron shrinkage as it cools so real patterns are made larger than the desired casting dims), one would assume an original lid, being larger than the copy pot, would likely not fit properly. Lid/pot joints on Griswold DOs were pretty impressive tolerance-wise, so one would expect them to fit either a Griswold DO or a slightly larger diameter pot, but probably not anything even slightly smaller. The other thing that I see is the handle appears not quite as well-done as I would expect from Griswold, and it's the one thing about a lid that Wapak would have been on their own in making it, as they would have had to fabricate their own removable "prongs" in order to create the molds.
