Crown Jewels is proud to present, in both the May and June centerfolds, color pictures of some world class insulators.

CD 151 insulators are classic in shape, representing a transition between early day threaded insulators and turn-of-the-century styles. The curve of the dome and the flare of the skirt remind me of CD 131 's, made a generation earlier.

But the pictures we present here for your enjoyment aren't just any CD 151's. These specimens are truly special. They are among the world's best examples of the style.

Page 33: (Top) 151's with purple swirls are rare enough. Finding one that is deep amethyst throughout is breathtaking. 
(Bottom) This outstanding red amber CD 151 is not embossed HG Co. It is an unembossed no-name. Little is known about this one-of-a-kind piece, except that it was found at the Whitall Tatum factory. That company isn't known to have produced insulators until 1922, well after CD 151 's had fallen out of favor with telegraph and telephone companies.

Page 34: (Top) CD 151's embossed NATCO (for North American Tel Company) are among the hobby's most popular insulators, due to the bright blue colors found in many examples. Peacock blue is a more common color. This one is deep cobalt.
(Bottom) Add a heavy dose of amber swirls to a batch of glass, and what might have been an ordinary insulator becomes a classic instead.

Page 35: (Top) Collecting insulators that are full of milk is a popular topical in the insulator collecting community. CD 151's are no exception. 
(Bottom) What a spectacular amber swirl! Nice contrast to the pastel colored insulator.

Crown Jewels will present eight more world class HG Co CD 151's for your viewing pleasure in June. (Think of it as our version of a swim suit issue.)

The insulators shown in this issue are owned by Tommy Bolack of New Mexico, and Tim Wood of Oregon. Photographs are by Carol McDougald.
