N107. Gillott 291 Nib Small, delicate nib for very small script (x-heights under 1/16"). Requires very light touch to keep it from catching on the upstroke. Useful for retouching letters made with larger pens. The Gillott 291 is stronger than the Gillott 290 and is probably more useful for script.
N72. Gillott 303 Nib One of the most popular nibs for copperplate. Good flexibility - not too stiff, not too flexible. Very thin hairlines and good swells. Works for scripts 3/16-1/16". Sharp point, but will work on slightly textured surfaces. Tends to catch on upstrokes.
Mentioned by Eleanor Winters in her Mastering Copperplate Calligraphy (B1109). Satisfactory for Spencerian Script.
N74. Gillott 404 Nib A popular nib. Fairly stiff nib, suitable for writing at x-heights from 3/16" to 1/4", on all surfaces from smooth to textured. Good choice for beginners (or those with a heavy hand.) Because they require more pressure to create the swells, stiffer nibs are easier to control. Thicker hairlines than others, making it a good choice for work for reproduction.
Recommended by Eleanor Winters in her Mastering Copperplate Calligraphy (B1109) for beginners and professionals because they "provide fine line quality without being too fragile." Satisfactory for Spencerian Script.
N75. Gillott 659 Nib This tiny crowquill nib is good for x-heights around 1/16". It is more sturdy than other small nibs and less flexible. Can be used to write on somewhat textured paper. Is smaller and less flexible than the Hunt 108, another crowquill.
Because of its tubular shaft, the Gillott 659 requires a special holder, Gillott Holder #51 (H75).
N76. Gillott 1068A Nib Very stiff nib. Ordinary pressure will create a monoline script to a script with just a slight contrast between thicks and thins. Can produce moderate swells with enough pressure.
