A Good Example of Continuing Research and Discovery are KERR Insulators

Reprinted from "Crown Jewels of the Wire", August 1997, page 7

As a follow up to an article in the February 1997 "Crown Jewels of the Wire" by Mike Harris regarding the Kerr DP1 Saudi insulators with the flat top, and referencing the Kerr information in "Insulators: A History and Guide to North American Pintype Insulators" states that near the end (1975) of Kerr making glass insulators, flat top variations came out due to horseplay on the production line... while, Michael Harris shows a flat top insulator made for Saudi Arabia in Dunkirk, Indiana from 1975 to 1978 and four Kerr DP1's in a purple and red coating. 

The dates are important, since I purchased an insulator outside of Cape May Courthouse, NJ, from a man who got it from a long time employee of Kerr Glassworks in Millville, NJ. This insulator is a flat top CD 122 (F-Skirt) Kerr No.2 (R-Skirt) Made in U.S.A. 3 72. with the same red and purple coating. However, this is a 1973 production piece according to the embossing. This does not coincide with the production dates of the CD 155. By the way, I bought a second CD 122 Kerr from an old timer at a cruddy old barn an hour or so later.

Should anyone have further information, please let me know.

More Kerr discussion from Richard Wentzel, Millville, NJ... 
I don't buy the frosted insulators for Saudi Arabia story, It's been my experience [as an extensive researcher of Whitall Tatum, Armstrong and Kerr manufacturing} that plant employees will tell you anything they can think up, especially when they're trying to sell you something. It's too easy to frost these things in acid. I must have seven or eight different styles. I can't imagine any breaking during the process.

In 1975 a man named Max wanted a box of insulators so he went by the warehouse and picked out a box and brought it home. 1 now have the box and 26 Kerr TS's. The molds are 1 through 18 72: . The photograph shows the original box and insulators. The side of the box is marked:
