Waterman’s 18 PSF “Press Self-Filling” Fountain Pen
New York, USA, c. 1915–1918

Introduced as Waterman’s early lever-fill “giant,” the 18 PSF pairs the firm’s newly adopted Press Self-Filling system (PSF) with a massive No. 8 nib—among the largest standard nibs of the era. The model code reflects Waterman’s pre-“5x” nomenclature: “1” for black hard rubber and “8” for nib size; shortly after, the line was renumbered to 58 when Waterman standardized “5” to denote lever-fill. Typical features include a boxed lever with the globe-logo tab, crisp barrel chasing, and a long, straight cap and barrel that prefigure the later 58’s proportions.

Historically important as a transitional piece, the 18 PSF marks Waterman’s shift from eyedropper and pump fillers to the lever system that defined its interwar production. Collectors prize the model for its scarce PSF imprint, impressive scale, and authoritative writing feel—an object that captures the moment when Waterman fused late-Victorian materials with modern, reliable filling engineering.
