This is a picture of a CD 127 embossed "W.U.T. Co. / Cauvets Pat / W. Brookfield" embossed on the front dome and "Feb 22 - 70 / No 55 Fulton St N.Y." on the back dome. This is what I will call the "knob" dome style and was found on the Central of Georgia Railway telegraph line. I found maybe 15 or so of this design variation. There is no mould mark and were found only in ice aqua glass which was very clear. I have found several different size embossings so have concluded that this was a design change and not a single error mould.
