This lovely nut spoon is by National Silver Company. It has a triangular shaped bowl. The slotted spoon is 4 1/2" long and the bowl is just under 2" wide. It has a delicate pattern design, although I was unable to locate the pattern name.
The back of the spoon handle is trademarked National Silver Co. and KES. It has usage marks, but nothing to keep this lovely piece hidden. It is in very good vintage condition.
