I have an original 59-page softcover Locke Insulator Manufacturing Company catalog for 1907. Catalog includes both glass and porcelain insulators, pins, brackets, bushings, break-arms, tubes, and panels for wall insulators. Cover has some writing and an ink stamp on it. Asking $300 trade value. If you don't know what I collect, you haven't been paying attention. Email for want list. Catalog was sold at the Franklin National.
