Vintage cufflinks by the Norwegian silversmith Niels Erik Elvik. His items are very collectible and these 830 quality silver cufflinks are very unusual having a goat herder calling his goats in the mountains on both sides. The bar between the sides holds one end solid and the other moves freely for ease of use to put on. Each side measures 25mm x 12mm and gross weight of pair is 6.8g. The bars are stamped 830S and the makers mark for Niels Erik Elvik.
