I became re-interested in stylograph pens, prompted by the post:
Photos attached are of my first attempt at using Koh-I-Noor nib assemblies to create stylograph type pens that would also accept Esterbrook nib assemblies. The material I used is vintage old stock cebloplast with aluminum hardware to bring out the white in the material.
The feed uses standard Rapidograph refillable cartridge.
Comments and questions are welcomed.
