This Western Union No. 5 (CD no. 125) was made between 1893 (patented 'drip points' on base) and 1919 by Hemingray.
The pre-drip-points ones have their December 19th, 1871, patent, and the later ones from about 1919 on are renumbered to No. 15.
This also fits in my May 2nd collection of insulators (patent date on back.)
I collect them as my dog Steve, in my profile picture, died on May 2nd, 2011.
