Here is what looks to be a CD 143 [020] GNW however there is just the faintest hint of threads. The diameter of the pinhole is larger than a threaded piece and just slightly larger than the threadless pinhole of a few other pieces I have. There are fold lines of glass inside the pinhole and the piece is in its original found state so I do not believe it was altered. I do have a mold match of this embossing in a threaded piece. If anyone has any additional thoughts or theories, please let me know.
