I would recommend buying a new touchdown converter from www.penhero.com. The problem with new old stock (NOS) is that it is old, and old means that rubber parts may have aged beyond their expected life.
This is often the problem so easily fixed with a new converter. Or you could try cartridges (and if you like diffrent inks, fill them yourself).
