Deep true red glass CD 102 style pony insulator embossed "VTS Industrial Co Number No 8". I understand these were produced back in 1977 for the VTS Industrial Co. in Arizona. The red color was likely created by adding cadmium-selenium red in the glass batch. There are some milky swirls in the skirt that show well. Books for $175-200. Blowout this evening for $125 plus shipping which will be under a pound and therefore relatively inexpensive. First email as always! PayPal welcomed. Contact me first for details.
