CD 145 [040] AM. INSULATOR CO. N.Y. DOUBLE PETTICOAT / PAT'D SEPT. 13, 1881, NOV. 13, 1883. Sporting some milky swirls and an out of round base that does not wobble. V on the dome with a lack of threads at the top of the pinhole. Inner skirt underpoured as well. Distinct period in the center of the skirt just below the wire groove. It shows just slightly to the very left of the picture. Perfectly centered from the mold lines so I believe it to be deliberate. Price $20.00 plus shipping (or no shipping if you are going to the Shrewsbury show this Saturday). First email as always. PayPal welcomed. Contact me first for details.
