Here is about the only legit true red insulator in the whole hobby that isn't altered.CD 102 VTS industrial pony in milky ruby red. These were made as giveaways in the 1970's by a telephone company. They came in 2 colours, peacock blue and ruby red, but they also had some come out in milky ruby red. This is one of the milkies. Pinhole is actually threaded and will fit on a standard American pin. These were never intended for actual service. Condition is pristine mint. Lots More pix on req. First mail to me.... $255 postpaid in USA/CANADA, other countries I will assist with shipping cost.
