Griswold skillet

Just picked up a chrome? Griswold 7 Skillet. Block lettering with a mold? number 701. Is there any way to date it and/or know if it's chrome or nickel? There is some flaking or pitting of the plating. Can it be replated?
Sorry I don't have my my camera with me.
Thanks for any info. Rob
