ANTIQUE GLASS TELEGRAPH INSULATORS, Paul's Pack of THREE! No. 9 model by Whitall Tatum, Made in USA

Available here is a set of 3 mid-century vintage CLEAR GLASS TELEGRAPH INSULATORS in the AMERICAN CLEAR GLASS No, 9 STYLE by Whitall Tatum. They have been packaged away for many decades, and these three are considered in excellent condition, no chips or cracks on two insulators, but there is one insulator with a small chip on the outer lower side edge, (see last photo). The chip is smoothed over now and does not detract from it's displayability, and is included in this sale because I thought it was important to try and keep them all together. Made in USA. Price is for ALL 3

GLASS TELEGRAPH INSULATORS were used to prevent electricity from flowing from wires to supporting structures like poles or towers, ensuring the safe and efficient transmission of power and telecommunication signals. 

HISTORY OF WHITALL TATUM COMPANY: Whitall Tatum entered the insulator manufacturing market in 1922, mass-producing them for use on power and communications lines across the country. Armstrong Cork Corporation purchased Whitall-Tatum in 1938, continuing insulator production under the Armstrong trademark. Production continued after a 1969 purchase by Kerr Glass Manufacturing Corporation until about 1976.
