Old hand tooled metal covered casserole dish

This piece is a mystery piece to us all. It is made of metal, not sure what exactly, could be silver or tin. No markings of any kind. It is very elaborate and lid fits nice and tight. Not even sure of the age. Measures 7" tall to the top of the finial, and measures 13" long handle to handle. Excellent condition, and no pitting, dents or damages.
