This is a very hard to find piece and its embossing (100) with the B. T. Co. of Can blotout both sides and diamond blotout on both sides. As seen in the pic it has nice amber swirling throughout the insulator. It has 2 dome dings and wee lower wire ridge scrape otherwise its VNM and displays great. Yours for approx. half book price $45.00 + shipping.
