Some danish auction houses attributes the design of this adjustable wall light to preben fabrisius and jorgen kastholm. Being manufactured by nordisk solar in denmark this attribution it is rather plausible. However we have not been able to confirm this since the ns period catalogues are incomplete. the light has a label from ns, its original porcelain socket and a fully adjustable shade. It made from stainless steel partially black lacquered. Measurements: d: 10, h: 22, dept: up to 26 cm. This piece has an attribution mark, i am sure that it is completely authentic and take full responsibility for any authenticity issues arising from misattribution, european plug (up to 250v).the wiring of this item may be original and might need replacement, if not specified otherwise.
