Lot#35 CD 133.1 PAT APP FOR VERY BUBBLY This insulator is VNM, but very crude. It is also crammed full of bubbles and fizz. There is an eraser size indent in the dome, but it does not have any impact mark. I think something was left in the mold. There is a small flat open bubble in the base. After careful inspection there is a slight mar on the dome (above the 3). $95+ Shipping Now $85 + shipping
