Here is an absolute beautiful CD 145 H.G.Co/ PETTICOAT "K" mold. There are three different "K" molds, this is a variant of one of those. In the front center of the dome, there are two embossed rivet marks from a hammered rivet repair to the mold. It was surely late in the life of this mold as the embossing is fairly weak. I have seen two other exact examples of this insulator. Very clean blue-aqua with a nice milk stringer running down the front of the dome as well. One small flea bite on the backside of the dome keeps it from being mint. I am looking for a U-274 or U-274A
