Here i have for sale is the lovely vintage mottled green and black national pen co fountain pen. It is the "graphic" model and features a 14 kt gold nib from the renowned american pen maker.It hasn't been serviced or checked as i don't know how to do this. The lid takes some getting used to putting on it seems to need a push to get it connected and then a screw to secure shut. Any further information or pics just get in touch. This item is made of celluloid and gold.
