Hello
Just picked up this small shell motif salt dish with a gold vermeil on three rough looking dolphin feet. The feet look like they have been added later perhaps and originally only had the handles thought I am not sure. Thinking this was possibly some earlier Dutch mark. Has the zig zag silver assay mark, Capital N in circle and what looks to be a small house or cottage in a circle. No other marks are found. Any help would be appreciated on origin and age.
Thanks
Pauline
