Here are two more CD 154 insulators from Spain. These are both in the clean defined mold style. The straw piece is embossed E.S.A. on the front and C.T.N.E. on the rear. The blue one is embossed E.S.A. on the front but the rear skirt is embossed 76. I have a clear one in this style that is front skirt embossed E 19 and rear skirt embossed N.1. I was told by the person I bought it from that it is an insulator from Spain. Look at the dome glass on the straw piece.
