Very nice lite blue aqua coloured CREB blobtop here. Beautiful glass quality for such an old telegraph insulator with a little bit of white milky strings floating around the pinhole in the dome. Embossing is very nice and readable which is unusual for most CREB pieces.EID [19O].This is an embossing error with the "S" in St embossed reverse. Someone can call this insulator mint. I really cannot find anything wrong with this piece, but, I'll stick to the safe side and keep it at VVNM. $1O + $7.50 shipping.
