I love this cabletop marking on this COOK Insulator Co. piece. Besides another piece I'll show you this is a really neat marking. You may say big deal nothing fancy about that but think again. How much time and steady hand you would have to mark it on the side of an ear edge. Certainly something you couldn't do on a piece rate line to every insulator. Maybe they were happy and creative that day or just pride in their work. Whatever reason, I'm glad I found it.
