Early Farber Brothers Silvercraft oval hammered silverplate tray

Early American Silversmiths Farber Brothers rare hammered silverplate oval tray approximately 17.5”x 12” with an intricate border that is photographed from both the front and the back of platter. I have not attempted to clean it as many prefer to keep it as is with patina. It looks like it is in very nice condition. The hallmark on back is a little worn but still very legible. It has a rounded rim of smooth metal and then approx 1” thick intricate border with maybe gryphons, urns or vase and a lady or Angel with a harp and a floral scroll type design. Very interesting piece. I do believe if desired it would polish up very nice. I no longer Polish as many believe the value to be in leaving it alone. It does show some tarnish as shown. This is an estate liquidation. I am happy to answer your questions.
