This is an aqua three piece mould CD 127 embossed "W. Brookfield 55 Fulton St. N.Y." on top line in a circle around the dome and "Pat Jan 25. 1870 - Cauvet's Pat Feb 22 70 - " on the second line in a circle around the dome. There is a circle with a "0" on the top of the dome. This insulator was a recent purchase from John McDougald and is a different shape than the three piece mould CD 127 which I found in Georgia.
