Suspension lamp in Murano glass, Italy 1960s

Refined Murano glass suspension lamp from the 1960s. The lampshade has a semi-elliptical shape with a white and gold glass spiral. There is no trademark, however the glass processing refers to the design of Dino Martens for Seguso. The lamp is in good condition, glass intact, the brass structure has only small superficial scratches due to age and use, not visible when the chandelier is hung.
Wiring replaced, the standard E27 lamp holder is original.
