The Whitall Tatum Glass Company located here in Millville, New Jersey which was sold to the Armstrong Cork Co. back in 1938 has been sold by them to Kerr.

To the best of my knowledge this is the only glass plant still making glass insulators in the U.S.A. The runs are limited in quantity and variety so not many new Kerr insulators may be expected. Unlike the Whitall Tatum name which remained for many years after the Armstrong people took over the Armstrong name can be used for only I year on the molds. At present the only change has been on the T W which is identical to the Armstrong T W except that the front of the base now reads KERR TW. All insulators are in flint glass (clear).

It is my understanding that most of the new production is for export.
