Lodge with swirl marks

Picked this on up at an estate sale recently. Basically brand new condition, stripped it and re-seasoned it and it looks unused. Got the cool grind marks on the inside. Anyone know if this grind marks come on any other size pans, I have only seen them on the #8, Doug posted one recently almost a perfect match.

Lodge used to grind all of their skillets then offered them ground or unground and finally stopped grinding c.1990 or so. Less labor and time to not grind. That is rather rough grinding compared to the very fine grinding of most Griswold skillets.

The #10 SK Made In USA I've had for decades is an unground. The #10 I found last year is super smooth.
