For sale is a porcelain insulator with a grooved base somewhat the shape and size of a CD 143 and looks like Bennington ware pottery. I believe these to be a greatly under valued insulator. This piece is well over 100 years old and in mint shape, its an old timer, just has a glaze smudge on back. Asking $40.00 U.S. + shipping. I accept PayPal in family/friends mode and also checks.
