Here is a sectional view of a porcelain lightning arrestor. You can view exactly the same interior construction on the all glass units. I have a glass unit manufactured by Hemingray (Owens Illinois) and the glass cap is marked LOWEX. Thanks to Chris Hedges for sharing this catalog cut from Line Materials ca. 1940.
