While the Pelikan 100N occasionally turns up in grey, the grey variant of the older 100 is significantly rarer and barely documented in standard literature. With nib damage and leaking feeds, restoration at specialised workshops like Tom Westerich (penboard.de), Lutz Fiebig or Werner is recommended. Repair costs can exceed market demand; sale to a collector or specialist dealer is usual as alternative. Professional reworking preserves collector value significantly better than own interventions.
