Box - .833 silver - Silver Box 833

I offer an old, silver, Dutch box (table box). The box is unique and intricately decorated. It is made of silver of 833 fineness. The weight of the box is 253 grams. There are assay marks on the box. The box is in very good condition. I cannot determine its age. It has been in my family for many years. It is in very good condition. E.g., any customs duties are to be paid by the buyer.
