Unmarked Wagner Lid - #9?

I've been having trouble finding a lid...saw this one and snatched it up.

Pretty sure it's an unmarked Wagner...the only mark on it is an "X" underneath, dead center.

The closest thing it fits (that I have) is a #9 Griswold.....so I'm guessing it's meant for a #9 Wagner. Does anyone have one to confirm?

It's Wagner.

Thanks Doug! I was hoping someone with a lid/skillet or lid/DO combo with an "X" could confirm what it's for.

The lid has spout covers, so it's for a skillet. My guess would be that it might be for a #8 deep skillet. Deep skillets' top diameters were in many cases larger than that of the same size regular skillet, if the maker did not change the angle of the sides to allow the same cover to fit both deep and regular.
