This insulator is a CD 160 Embossed on the front; "H. G. CO. PATENT MAY 2 1893" and "PEITTICOAT" on the back. It is the spelling error Peitticoat listing [100] in the book. The color is a light jade aqua which is a hard to find color. The insulator is in VNM + condition with only a tiny flake off the back of one drip point and a microscopic outside base edge flake. This is from my personal collection and came from the telephone underbuild on the Muncie line from Hauser Lake Dam near Helena. Priced at below low book price at $230.00 plus shipping. Payment by PayPal Friends or check. Thanks.
