CD 123 E.C.& M. CO. This dark AQUA insulator has a very bold button on the back and it has a Very small Surface stress crack that is above the "M". I believe it was caused by the little air bubble in the glass directly behind the center of the crack. There is absolutely no impact evidence!! The base is bruised in a few spots but as you can see in the second photo the glass is present. Still a very good buy at only ---$225.00--- DON'T WAIT FOR ME TO PUT IT ON SALE, THIS IS THE SALE!!!!!! Buy with confidence … We do not sell altered insulators! Buyer to pay all shipping and insurance costs (U.S.A. and Canadian shipping only). PayPal, Money Order, or Cashier's Check.
