We offer only a limited selection of parts. The main reason is simple: most vintage pen parts aren't interchangeable. They exhibit a maddening range of variations, and often as not even a correct original part must be hand-fitted. In most cases, it takes as much time to figure out what a do-it-yourself pen repairer actually needs as it would take to do the job ourselves, so please don't take it amiss when we ask you not to inquire about pen parts other than those listed.
