This is a nice 'Narvik 1940' remembrance/souvenir ring (Siegelring). The silver ring is nicely marked and showing three hallmarks. The first hallmakr is the silver hallmark, this one is hard to read but is most likely '830S', the second hallmark is the manufacturer 'Lo' indicating production by the company of 'Brødrene Lohne' from Bergen (Norway) and the third hallmark is showing the numbe 'Nr.375'. These rings were privately purchased souvernir items, bought by German soldiers during the occupation of Norway. The ring is showing the initials of the soldier: 'F.W.'. Nice original ring in good used condition!
