Default Re: Drawing Trader Sheets back in the day.

More years ago than I care to remember, I used to draw circuit diagrams for myself using Rotring / Rapidograph pens with a variety of line widths and a range of coloured Indian inks. I still have the equipment somewhere, though i suspect the inks have probably dried up. The ink reservoir in the Rotring pens was a soft(ish) translucent plastic cylinder which seemed impervious to the effects of ageing - unlike the rubber bladder used to store ink the the fountain pens of the time.
