This is a #12 Sidney Script Logo in great condition. It has been cleaned in a Lye tank and then a quick Vinegar soak, then seasoned once with Grapeseed Oil.
I do not have an electrolysis tank, but I think one would finish getting rid of the little bit of carbon that is still on there. The cooking surface is smooth, with very light pitting that will not affect the cooking surface at all. There IS a very tiny wobble side to side on my glass cooktop, but no wobble front to back, so I would not call it a "spinner". This is a great piece! In my 10+ years of finding and reconditioning cast iron I have NEVER run into a Sidney Script piece, much less a #12.Take a good look at the photos, I used my best camera to take those so hopefully it will be clear enough for you.
