I would be grateful for any help in identifying this little pin. The butterfly's wings are enamelled in brilliant blue, with detailed marks beneath the enamel, the body in a paler blue. The metal tests for silver. I am sure the mark is Scandinavian, but cannot find it in any of my reference books. It looks a bit like an eagle? with what I think should read '830S' beneath. Any assistance gratefully received. Kind regards, Judith
