The mark is on the back of a kitchen fork handle. Im sorry the image isn’t great, but it was the best my camera could do.
It is a bird with it’s fetherd wings open. Below it are 3 circles, one below the other. The first has a B, the second a 2, and finally an S with what looks like an L through it. Kind of looks like the American Dollar sign. Below that is a diamond with an R and small 0 or o next to it.
On the handle lower down is Potosi Silver L&S.
What is this hallmark mean? Country, make etc. Any input. Thanks
