Hi All, Got a MB 149 filler nob with a broken helical rod still in it but broken so there's only about one inch left still fixed to the inside fixing. I can still see the C clip in place holding the remains of the old helical rod. Does anyone know how I can replace the old broken helical rod with a new one I can get from Roger Wolff at Custom Pen Parts. May be someone out there has already done this job? regards Roberthansjorg
