Hello all. I need help identifying the hallmarks on this vase. The only thing that I was able to figure out, please correct me if I'm wrong, is that N.S. stands for Nickel Silver. Thank you very much in advance. https://i32.servimg.com/u/f32/19/82/59/29/img_3914.jpg https://i32.servimg.com/u/f32/19/...
