Hmm, a Wagner. Good catch, I was guessing a Griswold at first too with that marking on front and the handle style.
Looks like a nice a pan, them old ones usually have lots of pitting, good to see one so well cared for.
And possibly worth it. My mom has a collection of cast iron from her mother, my dads mother and various and sundry grandmothers and aunts. All old Griswold and REAL Lodge stuff, not the crap Lodge they sell at Cracker Barrel nowadays. She had a big new Lodge pan and the handle snapped off one day. It apparently had a huge void.
