New England Telephone & Telegraph toll insulator in a nice shade of green. I photographed it next to a CD 104 for color contrast. It's in very nice condition with just two small and shallow doinks to the wire groove (I have photos of these, just ask). Displays mint from the front. Crisp embossing, a very nice example in a color that is not as common. Asking $20 + shipping for the CD 121 only. PayPal no fee accepted. E-mail with any questions and thanks for looking.
