L to R: CD 164 No Embossing in sage green with amber swirls, CD 210 No Embossing in sage green.

Both of these insulators have been attributed to be manufactured by the California Glass Insulator Company. Both have been typically found in sage green. An example of the CD 210 in sage green glass was dug at the factory site in May 2019. For patent information, see http://reference.insulators.info/patents/detail/?patent=U1229272

In the 2011 edition of the Price Guide, a new color was listed for the No Embossing CD 164-- aqua. I would like to obtain an example.

There is also an unlisted color for the No Embossing CD 210. It is smoky gray. It was first described in a September 1970 issue of Insulators, Crown Jewels of the Wire article on collecting top tie communication insulators by Greg Kareofelas. There is a black and white photograph of it in the article. I am looking for this color example.
