Montblanc has in the past carried out nib exchanges and repairs (e.g. of leather parts) of the Limited Anniversary Edition 1924 without problems; reported is, among others, a successful nib exchange in spring 2004. A direct, friendly telephone enquiry to Montblanc service is the recommended path, especially since these pieces have not been newly produced for some time. Warranty periods should be heeded; nevertheless, generous handling is possible.
