I purchased this bottle years ago with several insulators at an antique show. I display it in my hutch along with a number of insulators. I have not been able to learn much about this bottle. As you can see, it is a corker and the mold line stops short of the lip. Do any of you collectors have any information about this bottle that you can share? It is unmarked and has three numbers on the bottom that may be 264. I had always hoped that it was connected to one of the glass companies that made insulators. Thanks!
