A successful "catch" in Poland, two CD 578.1 from the glassworks J.Stolle Niemen, unusual and interesting U-1956 with fuse clamps and, so far, an unidentified "spooke" type, the only visible marking is the letter C in the triangle on the left "ear" side and the number 12792 at the bottom. If anyone knows anything more about this last insulator, please contact me.
