cast iron skillet

There were actually several assorted iron skillets found in that 'cabinet w/bad plumbing' along with the dutch oven pot -- this one being the only one of them really appearing to be "vintage/old". (the others being unmarked and likely much more contemporary, from Harbor Freight or somesuch?)

It is about 8-1/4" round, 12-1/2" long with the handle. It has obviously suffered greatly during who-knows-how-many years spent *not* on a stovetop frying bacon...believe it or not the pics here are *after* I took a wire brush to it to scrub away the worst of the rust it had on it when recovered. It is marked with a number "5" on its underside near its edge, also what might (?) be a letter "C" above that.

I can't say I have any intention to try to restore the poor thing to active duty (too much work, and I've already got other iron skillets I *can* use?!) but I kinda think it might be a 'keeper' anyway...? ;-) :-) :-)
