Here is a beautiful LOWEX version of the CD 230 glass insulator. Affectionately called Frog Eyes by collectors, this one is top shelf. I see NO signs this guy ever saw service. There is some streaking in the amber coloration in her skirt plus some nice seed bubbles for additional curb appeal! This IS the upgrade. Asking $60.00 and that's shipped price. Don't wait fer a sale. It aint gonna happen! ALL forms of payment happily accepted!
