This is a vintage midcentury modern silverplate serving dish with very clean, simple lines. It is 11" wide and 5" tall with the knob on the lid. The knob is black bakelite. The base is marked Sheffield Silver Co Made in USA EPC. It does not have the glass liner insert. The dish is in very good condition, there are light scratches from use. It was a wedding present in the 1950s to the original owner. MBR.
