I know there are several "Emporer" pens out there, but Woodcraft sold one--they do not sell any more and I don't know if anyone else sells this particular kit? It has just a single tube design and uses a 11/32 tube/drill. I have two clients who want more of this particular pen. Woodcraft just says it's not in their system any more. If any of you have this particular kit and are interested in selling them, please let me know about that as well.
