#1594 CD 104 NATIONAL INSULATOR CO. PAT JAN 1 & OCT 7 1884. Aqua.
Base embossed with precise, very small lettering. The patent dates are in reference to the process of forming the interior threads.
A handful of insulator designs are marked with the "National" name, all being scarce.
A couple flat base chips (see second photo) are positioned in the unembossed areas. Vast majority of the embossing is intact with only the "PA" removed. Two small open bubbles on the base edge (see 3 o'clock position in second photo) graze the tops of three letters.
A scarce insulator!
