This insulator is a CD 280 Embossed on the front; Hemingray Patent May 2 1893 and High Voltage Triple Petticoat No 1 on the back. It is an aqua color. The insulator is in very near mint condition with only 2 drips with tiny flakes off them and a faint narrow 1 1/2" long etch mark on the back. A nice displaying small power piece. Priced at; $30.00 plus USPS Ground shipping cost. Thanks.
