For your consideration is a vintage Westinghouse high voltage lightning arrestor cap, as shown in the photos. It measures approximately 5 3/4 inches diameter and 2 1/4 inches tall. I found this item rather randomly so I don’t know it’s history. It has a few minor imperfections but is in overall good condition. This is a nice vintage item that you are purchasing as-is and as-pictured. Thank you for your interest.
