This piece I happened to find about 7 years ago while digging an insulator dumpsite I located behind an old depot they had razed. Must have been a burn pit for arms because I found a lot of big arm bolts, slagged arm braces, bits n pieces of other hardware, lots of melted insulator glass plus LOTS of dark ash laden soil. This, plus an old style 121 Hemingray patent date toll were the only intact insulators I found. Check out all the fizz!
