Pendant light in copper and black metal. denmark 1960s

A small pendant light made in copper sheet and black powder coated metal. It has the classic hammerborg/f&m style openings between the layers for the light to reflect on the copper sheet along the sides. The bottom is covered with a plastic glare protection grid. I have not been able to find any information about this light and I have never seen it before. As seen inte images it has quite heavy patina. Both marks, scratches and dings here and there. Still I find it to be a very charming and interesting light. It almsot has a bit of prototype-look to it. Standard e27 light bulb socket. Worn condition but well functional.
