A friend of mine has a nice Parker Duofold mechanical pencil, made around 1950. He is about to run out of leads. My calipers measure the existing leads at 1/20 inch, 0.05 inch. Does anyone know where Imperial leads are available? The 1.18 mm metrical gauge will work at a pinch, but the real thing would be preferable.
