I need help in locating the mark on a silver plate tray. The mark consists of two hands "facing" each other. I have found single hand marks but not a mark with two hands "facing" each other. The tray, I believe, is English. Not including the handles the tray measures roughly 24 inches (60 cm) x 18 inches (45 cm) and weighs 10 pounds or about 4.5 kilograms. I am showing the tray, a closeup of the design and the mark. I can see no traces of copper coming through the top layer of plate, so most likely this is not Sheffield. Any help would be appreciated. Thank you.
