Hi ICON, I have this foreign white porcelain insulator and I wanted to know if anyone knows what country it was manufactured in and / or what other countries it was used in ? I can't find it in any of the books. This unmarked insulator is 3.5" - ( 9 cm ) tall by 2 1/4" ( 6 cm ) in diameter. Any help with identifying it's origin would be greatly appreciated! Thanks, Mark
