It turns out that the Hemingray 42's, Tutum No1's and Armstrongs might have to share their role as the most common insulator out there in that our leading expert on alien pin type insulators has discovered that on a planet 47 light years from earth hunderds of thousands of these bird mouth shaped insulators seem to live on the telephone poles of this planet. This CD 5000 insulator is a pin type insulator that is about the same size and weight of a Hemingray 42 insulator and some of them have been found so far on the planet in the colors Aqua and Clear.
