Two CD 472s (and possibly one CD 471? in the center) from Poland, the dark green "Conehead" in the center has a very similar shape to the CD 178 "Santa Anna" insulators, just on a smaller scale. It is about 3 1/2 inches high x 3 1/4 diameter.

The left one has a spherical top. the center more of a "Conehead" shape, the right one is more oval in profile. These are approx 3"H X 3 1/4"D. . No embossing, on the spherical top, he two others are crown-embossed IL.NS-80.(the diameter of the skirt is 80 mm)
