This engraved silver plate is engraved with a floral design. The commemoration engraved on one side of the cup reads, "John Sharp McNab 20th October 1878. The handle is quite decorative appearing to be a swan neck and head. The bottom is marked JB & S BP and 169. I believe this is the mark of the Jonathan Bell Sheffield Silver Company. This cup is in excellent condition. It measures 2 5/8" x 3 1/2".
