Vintage 40s Watermans Reservoir Fountain Pen #503. Book Keeper Black. Red Cap.

This pen is a Watermans #503 in black; this pen is often called the Book Keeper. All external gold details are gold plated and the nib is 14 carat. This is in very good condition; this has not been used for some time, so may need cleaning to some degree. Visually very good and reservoir lever works well. There is a little bit of wear to the pen top, where this has been unscrewed over and over again, just surface wear and legitimate patination. Length: 5 inches/ 12.5 cms
