My dad called and said he saw something and I duplicated what he told me he saw. the bottle stopper is inside a sleeve of wood that allowes the stopper to stand on its own when not used, I also added an insert to the top which was a brass earing with the backing removed.
OK, but you might encounter problems using it with some bottles that have a wider O.D. I knew a guy that turned some similar, a customer bought 5, and returned all because they would not fit. Just food for thought.
