Pair of Magnus Aase Norway Viking Horn 830 Silver Salt & Pepper Shakers
Here is what I have learned in researching the stamp - 830S is the pure silver quality mark used before. Magnus Aase established his workshop in Bergen in 1899 and was eventually one of the country's best known silversmiths. In 1902, he and his brother Knut took over Theodor Olsen's business. Unknown to me is if this design was originally Theodor Olsens or Magnus Aase.
