The CD 154 is not something I've seen before. You may be aware of the two CD 154 varieties produced by Cristalerias de Chile. There is a slightly rounded dome version, like the one being offered here, and a flat domed version. The slightly rounded dome versions are heavy pieces of glass. The flat domed insulators appear to be a later offering by the manufacturer, as attested to by the logo-only late embossing found on some flatter domed pieces and the notably diminished glass content. What is unusual about the CD 154 for sale in this listing is the absence of an "N.42" embossing. The lack of an embossed style number could indicate that this is one of the earliest Cristalerias de Chile insulators in the CD 154 style. VNM+ condition. $32 plus postage. SOLD
