An original English-made Mentmore Diploma fountain pen in black, fitted with a nib marked “Warranted 14 CT” and using a traditional button-filling mechanism.
eBay condition: Used.
The pen shows age-related surface wear, light marks and some dulling to the black finish. The clip and trim have tarnishing and wear to the gold-coloured surface. The engraved Mentmore Diploma and Made in England markings remain visible.
The nib has age-related discolouration and traces of old ink. It appears complete, but nib alignment, ink flow and writing performance have not been tested.
The button-filling mechanism is present, but it has not been operated under pressure and the condition of the internal ink sac is unknown. Given the age of the pen, it should be assumed that cleaning, servicing and replacement of the sac may be required before use.
This pen is sold untested and as requiring inspection or servicing. No claim is made that it currently fills, holds ink or writes correctly.
No ink test or water-fill test has been carried out. The filling button has not been forced, in order to avoid damaging a potentially hardened internal sac or pressure bar.
The pen will be supplied empty of ink, carefully protected and securely packed for dispatch on the next working day. Weekend orders will normally be dispatched on Monday, excluding Bank Holidays.
Returns are accepted in accordance with the eBay returns policy. Please study all photographs, as they form an important part of the condition description.
Collector’s Note: Mentmore was a respected British pen manufacturer, and the Diploma was one of its longstanding traditional fountain-pen lines. This early button-filling example retains its characteristic clip emblem, barrel imprint and removable blind cap.
