In the second picture I see a mark that looks like a C or part of an 0 just off the center line at about the 3 O'clock position. maybe I am imagining it or it's a scratch in the seasoning. If there is a number there, this might be a Vollrath, but the handle is different than any I've seen. Sorry I can't help on the ID of this skillet. Maybe some of the other member will take a second look and see something I'm not seeing.
