This is a used Christofle silver serving tray. I believe it is silver plated. It has been used many times over the years and shows heavy wear. There is an emblem or crest in the middle of the tray and it appears to be an anchor. Due to the wear it is hard to see now. This tray weighs 3 pounds 3.2 ounces and measures 18 x 13.5 inches. Please see photos.
