This box is 11 x 6 cm by 3.5 cm deep and was given to my mother in 1950s. I think is may come from the far east. Sorry I am struggling to get a good pic of the hallmarks!
Chinese Export silver and your pictures are nice. The marks pic is upside down, believe that's one of several different marks used by Wang Hing (late 19th-early 20th century).
