Here's an odd looking power piece produced at the Victor plant. This beefy insulator features a 1 1/2" pinhole and an excellent R = 00 marking centered on the side of the insulator. The glaze is shiny and clean with no apparent damage that I can see. Used somewhere in the industrial areas of Buffalo, NY. Add this to your collection for $75.00 postpaid. First e-mail gets it. Please, no PayPal. Thanks for looking!
