Pair of CD 145 [040] Dome (V) Base AM. INSULATOR CO. N.Y. DOUBLE PETTICOAT / PAT'D SEPT. 13, 1881, NOV. 13, 1883. The aqua one is sporting some milky swirls and an out of round base that does not wobble. The blue one has some white crystalline in the glass. Both have near non existent threads near the top. Both are from the same exact mold and have a distinct period in the center of the skirt just below the wire groove. I have positioned them so you can see it on the left. Perfectly centered from the mold lines so I believe it to be deliberate. The V and base embossing also line up in the exact same place. Price $40.00 for the pair 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.
