Antique Napkin Ring Silverplate K & Co

Antique silverplate napkin ring with a hallmark that looks like K & Co Quadruple Plate inside. Very elegant, with snatched waist shape and raised letter or design on a shield shape on front -- it doesnt look like a monogram, but could be the letter G, I guess. -- 1 1/4" wide -- Nice condition with overall moderate to heavy tarnish. Perfect for Thanksgiving or Christmas dinner!
