About Conway Stewart
Conway Stewart was founded in London in 1905 by Frank Jarvis and Thomas Garner and became one of Britain's best-known fountain pen makers, using hard rubber and later colourful celluloid and casein. The original company wound up in 1975; the name was revived in the 1990s and, after a 2014 receivership, is now held by Bespoke British Pens, with pens hand-assembled in Emsworth, England. Current production is high-end, using marbled acrylic, celluloid and sterling silver with 18ct gold nibs, typically priced from about £400 upward.
How to fill the Conway Stewart 759
Fill it two ways: snap in a pre-filled international cartridge for convenience, or use a converter — a small plunger or twist mechanism that installs the same way a cartridge does — to draw ink from any bottle. The converter route opens up the entire world of bottled ink, which is where most of the hobby's color variety lives.
Choosing a nib size
Nib size determines line width, not writing pressure — fountain pens are meant to glide, never press. Extra-fine (EF) suits small, dense handwriting and thin paper; fine (F) is the most broadly recommended default; medium (M) shows more ink character and shading; broad (B) and stub grinds favor bold, expressive strokes and calligraphy-adjacent writing. The 759's gold nib will also flex slightly with pressure, giving line variation that a steel nib of the same size won't produce.
Keeping it clean
A quick flush with cool water every time you switch ink colors — and a full clean every 4–6 weeks of regular use — is enough to keep the nib and feed performing well. Inktend's cleaning reminder is tuned to a 21-day baseline and adjusts naturally to how often you actually refill.
Pairing inks with the 759
Because refills are quick with a cartridge or converter, this is a good pen for rotating through several colors rather than committing to one; sample vials work especially well here.
