S Kirk & Son STERLING Sugar Shell Spoon ~ Repoussé ~ NO MONO.  It is from my family silver I've opted to liquidate a bit at a time.  I'm sure it has been used, but infrequently.  We never kept a sugar bowl.  My mother believed it would draw ants.  We kept our sugar in a snug lid glass countertop canister and metered it out with a plastic 1/3 cup dry measure scoop.     I always ship in a box.
