The company producing these insulators was first known as the California Glass Insulator Company, located at Long Beach, California. They started production in 1912, and only a Pony style insulator bearing C.G.I.Co. embossing (No. 1 illustration) has been found. It is not known if any of the "California" embossed insulators were made by this company before their name change to California Glass Works in 1914. But due to the large number of styles having exactly the same coloring as the
C.G.I. Co. pony, it would seem very likely they did produce others. If this is not the case, then the California Glass Works must hold the record of producing so many known styles in so short a time, for they were out of operation in 1916.
Those of us living in California may have an advantage in collecting all of the styles, but the going is rough. Virtually no one has all of the 23 styles, though a couple or three collectors are near that ultimate point. The rarest items are numbers 9, 23, 17, 6, 19, 22, 20 and 21 in about that order.
To my knowledge, only one California with drip points (No. 9) has been accounted for, and only two two piece transpositions (No. 23). A lucky Bakersfield collector has both of these Items. The narrow groove, long skirt helmet (No. 17), and the small "Egg" (No. 19) are the next rarest, I believe. This guy-wire strain Insulator is embossed 10 CALIFORNIA above the groove, and PAT APL'D FOR below the groove.
(May 1969, page 12) Note the uncrossed "T" In PAT, which is the only embossing error found
in the California lineup, as far as I know.
The only two styles embossed with a size number are the two strain insulators, the smaller Number 10 size and the larger one embossed with NUMBER 15. The tolls are embossed with A007 above the name, though, and the wide groove signals have
AO11 in the same place. Also some of the signals (No. 7) have an "A" embossed on top of the dome. The only style having embossing on both the front and rear
is the California (front) Santa Ana (rear). It might be well to mention that not all of the Santa Ana insulators have California embossing also. The odds are against it, as after 1916 the principal user, P.G.&E. Co. had some other manufacturer produce this style for them. Most of the non-California Santa Ana
insulators are dark green, and many are unembossed.
Color wise, no company matched California Glass Works for variety. Whether it sun-colored, or came out of the batch that way, almost every color of the rainbow can be found. The most unbelievable and startling to the aqua-oriented collector is the real true lemon color found most often in the "Helmet". What is referred to by many as "S.C.A." ranges from light pinkish, to peach, muddy amethyst,
smokey, wine, and bright burgundy. The cool colors are green, aqua, and a blend of these, with blue-gray known
locally as "sage" from sagebrush. For those familiar with this plant of the West, you know it varies in color a great deal, depending upon its dryness and the light hitting it, but always "sage". Once in a while a "jewel" can be found having a combination of S.C.A., yellow and green glass.
No doubt I have missed or goofed on something, but I hope it helps a few collectors. They can envy the California specialist collector who has most of them, along with me. My California collection contains only 15 of the 23 insulators, and my hopes of getting many more are slim. If anyone has additional information, please share it by writing this magazine.
