Answer Thanks Charley --
We identify your insulator as a CD 160, these were smaller versions of the standard CD 162 style that are used for telephone, low voltage distribution and fire alarm circuits. Yours was probably made shortly after World War II -- CD 160's are very collectible with a trade value of $4-$5 or so. Whitall Tatum was based out of Millville, NJ and made bottles, insulators, and labratory glassware --See:
