Table lamp that we think is Swedish and from the 1960s

Extremely rare and very special table lamp that we think is swedish and from the 1960s. It is made of brass with a hard pressed plastic core and then it is built up with threads inside the shade so it almost looks like lightning. It's so accomplished and special that you won't find many of them around the world. (the first we've found in 7 years) It measures 23.5 cm in height, 7.5 cm in diameter and weighs approximately 885 grams. Normal signs of wear and tear, no defects or missing parts (we have not polished the brass) A bulb is included in the purchase (has a standard e14 socket) Packed securely and shipped with insurance.
