It's hard to be sure, but I wonder if a standard Rotring (a.k.a., Radiograph)
technical pen will work. Those were commonly used in plotters, for example I
remember using a Calcomp plotter with one of those. And those are obviously
refillable, and available in any number of sizes. Not to mention great drawing
tools to have around -- I wonder where mine is.
