Very nice, early piece of Western USA telegraph glass here. Very fizzy bubbly CD 123 which I believe to be the EIN[O50] square dome, straight skirt and clean wiregroove/G mould? Not completely sure since there are no letters to actually indicate which mould but there are no globs of glass in the wiregroove. Great swirls of amber in the side skirt of this. The threads are from the middle of the WG trough to dometop, from WG below is threadless. I would suspect that when they pulled the mandrel, they smoothed the threads out and away as they withdrew the mandrel leaving a threadless pinhole. The threads are so very faint in the pinhole that all you can feel are the tiny humps left where they would have been. There is some base damage which could be repaired if desired, there's a large, flat, thin flake that looks like a thumb up the mouldline at the side skirt and on the base there's a 1.5" inside the skirt bevelled chip, with a ghost fan bruise and small notch chip removed. The bruise is no glass missing and can partially be seen in the photo at base. Lots of annealing surface hairlines around the corner edges of the dometop. Displays exceptionally nice from the front despite the listed damage and is quite unique with half the threads not there. Book for this EIN is $200-$250,If I am wrong about the EIN and mould letter, please let me know! More photos on req. First mail to me.... $15O shipped in USA/CANADA, other countries I will assist with shipping.
