The moldmraks themselves totally give away that the mold is identical. Note, for example, that the Wisconsin Glass mold (the Palmyra bottle) is printed with a small "o" in "Co" but all capitals in Milwaukee "MILW".
The Northern Glass Works bottle has a re-worked area where "WIS." was originally written. However, upon careful examination, you can pretty clearly see where the "W" in "WIS." used to be! That is pretty conlcusive that these came from the very same mold.
Finally, my last photos. These show the other known hutchinson from the Northern Glass Works. It is a Kornburger. It has a cool dash - dot - dash design in the slug plate. It does not have the stridations, though.
