I believe this Amethyst water bottle is from the early 40’s. Most water bottles have necks that go pretty much straight up on the sides. I just have a few examples where the whole neck is stretched sideways so the neck joins the shoulder at about a 30 degree angle. I wonder if there was a specific finisher who created these or if it just happened from time to time. It has a great “earthy” color. You can almost see the brown in it.
