Another "spaceship" cable top insulator from J Stolle Niemen, formerly of Poland. A very nice cobalt blue with a bit of violet overtones. I've long heard rumors of cobalt insulators from Poland, but I never actually saw one, so I put the claims in the category of Bigfoot, and the Roswell UFO crash, very intriguing stories, but with no "concrete" proof. Att least this one DOES exist, and I'll leave the Sasquatches and Roswell ALiens in the "gray basket" (pun intended) for now ;-) It has a small chip on the bottom of the inner skirt. About 85 mm / 3/4 inches skirt diameter.
