This is my O.V.G.Co (Ohio Valley Glass Company) cd 112 glass insulator in light Aqua. This style is nicknamed the Keg.
CD 642 FOLEMBRAY No. 35/1 {France} (foreign glass insulator) Color: Forest Green Description: The right "arm" projection has been reattached, otherwise very, very near mint. Typical factory mold line grinding. This insulator from France is nicknamed the "Gingerbread man" as, at 5 1/2", it's the tallest of this "family" of insulators.
CD 145 AM.INSULATOR CO. (glass insulator) Color: Fizzy Dark Apple Green w/ a few Milk Wisps Description: Very crude base. Quarter-sized bruise centered in the wire groove with no glass missing; a 3" fracture in the outer skirt at the top of the inner skirt. A really neat piece with some milkiness over the dome and a few wisps in the skirt. Add the milk together with the fizz, and you get an interesting translucent effect! (#3544)
Not many people are aware that glass insulates against electricity. If you are one of the many who are not aware of this bit of fact, you are not alone. The
CD 221 WHITALL TATUM CO. (glass insulator) Color: Dark Red Amber Description: Minor scuffing on the base, a BB ding on the inner skirt. Whitall Tatum produced several styles in amber; the CD 154, 155 and 221 are the least common. Great condition for this rare Whitall Tatum piece! (#7254)
CD 214 TELEGRAFOS NACIONALES (glass insulator) Color: Dark Orange Amber Description: Excellent condition with only one chipped drip in the rear. A color that's always popular! (#0510)
CD 201 H.G.CO. in Aqua
CD 160.7 AM.INSULATOR CO. in Apple Green
U-816B LOCKE 23550 (porcelain insulator) Color: Chocolate Brown Description: A large piece that is 11" in diameter and 7" tall. Incuse marked "LOCKE / 23550". Excellent condition. There is a lead insert in the pinhole. These insulators were used in the Midwest. This is an odd piece that looks like a combination of a suspension insulator on the bottom and a power station bushing on the top! Given it has a pinhole, it is clear it was designed to be a pintype insulator. This is one piece that will stand out in your collection! [NIA] 100% of the net proceeds will be donated to the NIA.
CD 317 CHAMBERS (glass insulator) Color: Tealy Dark Aqua Description: Pinky-sized base flake; the damage-prone groove is perfect, as is the rest of the insulator. Some might call the color Teal because it's so deep and rich; you can decide for yourself! (#8035)
CD 178 SANTA ANA (glass insulator) Color: Rich, Deep Yellow Green Description: Skirt flake, otherwise VVNM. An attractive color for this "spaceship" style. (#10005)
CD 141.7 TWIGGS (glass insulator) Color: Crystal Clear Description: Factory mint. All of the Twiggs insulators were discovered with their bases ground flat. In this case, that procedure produced a 1" tall flake up from the base and a little base flaking. The Twiggs units in general were very well molded. This one is a bit unusual in that the pinhole is oval and off-center, and there is an underpour at the base. The Twiggs is a unique style that is coveted by collectors. It is also unusual in that it is "top heavy" with the "dome" being significantly larger in diameter than the base. The Twiggs is quite tall and will command a visual presence in your lineup of more traditionally shaped insulators! (#0228)
CD 162.4 1678 (glass insulator) Color: Deep Yellow Olive Green Description: 1/2" base flake and a little roughness on the inner skirt. Very good condition! These insulators are rising in value as people are beginning to appreciate their outstanding color and rarity. It's about as good as you can get for a 1678! (#0151)

A style of insulator known as a cable insulator which were produced for secondary power distribution that had a voltage rating of 6,600 volts.These particular flashed amber power cable insulators were produced by the Hemingray Glass Company in Muncie, Indiana around the 1930's - 1940's. Flashed Amber was a coating applied to the surface of the insulator while it was still hot. It generally results in various amber colors, which often results in giving the appearance of wood grain streaks on the insulator.The amber coloration was produced to color code a given circuit, often times to designate a different voltage than the other wires on the same pole. Although I did bought this particular insulator a long time ago in the 70's. I have personally found a couple of these same insulators along the old Erie Lackawanna Railroad in Ohio City, Ohio back in the late 1970's. Embossing (F-Skirt) HEMINGRAY-62 / ['LOWEX / REG. IN U.S. PAT. OFF.' blotted out] (R-Skirt) MADE IN U.S.A. / [Numbers and dots] Index # 110
CD 142 HEMINGRAY // TS_2 (glass insulator) Color: Carnival w/ Copper Liner Description: Very, very near mint. In an attempt to eliminate interference, several different styles of specially treated insulators were developed by Hemingray for the Western Union Telegraph Company, including CD 118, CD 142.4, and this style. An iridized coating of tin and iron was used with the intent to reduce water adherence. This is the less common [030] embossing variant with "TS_2" blotted out on the front skirt. A great experimental piece from Hemingray!
