I believe they went out of business quite a few years ago and the sons were selling leftover stock that wasn't sold, piecemeal. I have an unlabeled Cellini but it came with a stem albeit a crappy one that will need to be replaced one day. They are good pipes though. I would suggest you contact @RustiePyles CPG or @georged or any other member that makes stems and inquire if they would take on the project.
