This is a 17 1/4" oval silverplate platter. It is not signed or marked, and I have not been able to identify the maker or pattern name. The pattern is an ornate embossed design of shells, urns or lamps, scrolls, chains, and flowers. There are a few tiny spots where the plating has worn away front and back. The platter has been used, there are utensil marks on the front and light scratches on the back. MBR.
