Multi layered "space age" pendant light in brushed aluminum with red light effect, Sweden 1960s

A quite large (37 cm) pendant light made from seven aluminum rings, six in brushed aluminum and one with black matte lacquer. The inside of the light has a red surface creating an amazing red glow on the aluminum when lit. I have not been able to identify the maker of this light but it is well-built and reminds me of something early by Granhaga Metall. Good vintage condition with a few scratches and small marks but no dents or bends. Standard e27 light bulb socket.
