CD 200 CALIFORNIA (glass insulator) Color: Deep Burgundy Description: A small base chip and some roughness from a thick mold line with an associated annealing fissure that wraps around the umbrella as seen in view 3. This appears to be a factory flaw. This is a real tough California transposition to acquire in any color; get it while you can! (#7022)

CD 113 Hemingray
CD 1066 SEDIVER A22 {France} (glass insulator) Color: Glowing Limey Apple Green Description: Very, very near mint. A large 4" tall spool with a 5 1/2" diameter. The U.S. spools usually have the top of the pinhole broken out, leaving a rough edge, but this pinhole is carefully polished. Sediver is still active today, and since the early 60's, they have been doing business with utilities in the United States. This is a spool insulator which is unthreaded and mounts in a holder with a pin through the center. These were typically used to dead-end a power or communication line. An impressive piece and a great color!
CD 242 HEMINGRAY-66 (multipart porcelain insulator) Color: Hemingray Blue Description: A 4" area and a 2" area of drip chipping. Many of these are quite "beat up" and the damage/slices extend up into the skirt. The damage on this piece is pretty much limited to the base. The style number 66 indicated that it was designed to be used from 66 hundred to 88 hundred volts. (#0936)
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)
CD 158.1 CHESTER (glass insulator) Color: Bright Blue Description: Factory annealing fissure in the skirt, a few little dings. Great condition! This rarely encountered insulator appears to have been made for the Chesters by the Boston Bottle Works. The firm of Charles T. & John N. Chester, in 1855, continued the business established by Mr. John W. Norton who, in the early days of the telegraph, was largely engaged in the manufacture and sale of telegraph instruments and supplies. The wavy wire groove and three notches on the dome were designed to be used with a metal ring. (#5247)

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 143 CANADIAN PACIFIC RY.CO. (glass insulator) Color: Steel Blue/Purple Two-Tone w/ Amber Swirls Description: Outstanding condition. A beautiful insulator with a good two-tone effect. Purple areas can be seen throughout the piece. An amber ribbon in the dome adds contrasting highlights!
The glass insulator is one of many man inventions. However, like several others before and after it, it has gone extinct and is no longer used. Glass insulat

CD 175 HEMINGRAY-25 (glass insulator) Color: Aqua Description: The winner for the largest wire groove on an insulator! The purpose of the groove was to terminate multiple wires, and it occupies more than half the total height! Nicknamed the "Doorknob", this insulator is often found with some damage, but this one remains in excellent condition.
CD 151 H.G.CO. (glass insulator) Color: Ice Aqua w/ Purple Description: 1" skirt bruise and a large inner skirt chip, both in the rear. The rest of the drips are perfect and the rest of the insulator is VVNM. Some people talk about purple wisps in the dome? others talk about purple swirls? This insulator is nearly a two-tone! From the lower wire ridge up it is virtually all purple and the skirt is the typical Ice Aqua color. Charles was gracious enough to allow the people attending the 2012 Kansas City National to view his collection. Everyone, including ourselves, found their eyes were immediately drawn to this insulator! And you can see why... This is believed to be the most extreme example of a CD 151 with purple in the dome. It is just an amazing piece! You have to see it in person to truly appreciate it; buy it and see for yourself! (#4605)

CD 221 HEMINGRAY-680 / LOWEX (glass insulator) Color: Icy Green w/ Treated Top Description: The treated top insulators probably came out of the Hemingray dump, and there are a few little pings and a flake on the skirt. Great condition overall for one of these pieces from the dump! The saddle and the pinhole were treated with a semi-conductive material that was believed to have been designed to reduce radio frequency interference. Produced in 1940. This treatment was applied to Hemingray's 600-series of CD 219-660, CD 220-670, CD 221-680. The treatment apparently had little success, because few if any were put into service. And a great companion for lot 171! (#0956)
