Okay, here are two insulators that have us and another fellow collector puzzled. We purchased the two middle pieces about 3 years ago in Kansas. My mom purchased them because they were odd looking to her. Going through her collection last week, I stumbled on them again and we still don't know what's wrong with them. We thought at first that they were heated and slumped due to the heat but the threads and skirt are all perfect with no damage or melting done to them. The Embossings and styles match the CD 128's but they are shorter and fatter than the 128's. Anyone out there have an idea what might have happened to these two?? Maybe a mold that didn't work out? Why would anyone heat up a Pyrex 128? Any theories or ideas would be greatly appreciated. Anyone else have ones like them? Close up picture [id=148912449]
