Antique Victorian Sterling Napkin Ring

This is an antique sterling Victorian napkin ring in good shape with a few very small dents along the side edge. The only mark I see is 70 but it tested positive for sterling . It has beautiful engraving and does have the initials GWL in 1 spot. I am thinking it is a piece of Gorham but do not see the mark.Listed 7/24/23-7/26/23
