Insulators in Catalogs |
Many early electrical jobber catalogs had listings from various insulator companies. The table below provides links to catalog page images and a brief description of the insulators listed. The initial focus is on catalogs that include some insulators as these are more manageable in scope and many of the early catalogs are available in reprints already.
