Heres what I've found about this bracelet. It was apperently available in northern finland in 1943.
Walter rosenwald published a catalog that displays it. And a simmilar piece in poor shape without the bracelet itself was sold at a german auction. Here's a picture from the catalog





Two seperate collectors have tried to buy it from me, saying "name your price" .
But selling this is difficult, since the piece is so rare and in excelent condition.
