On the left is a sage green, unembossed CD 164 attributed to the California Glass Insulator Company. On the right is a Calfornia CD 166 in sage blue. This is the square dome mold with the style number A011 weakly embossed above "CALIFORNIA".

Aside from the identical glass color to California sage green, the unembossed CD 164 can be found with grind marks along the skirt bottom like many Cals.
