The RichardsPens Guide to Fountain Pens, Volume 2: RestorationThis book is an adjunct to the two excellent existing repair manuals, Marshall Oldfield and Da Book. It contains material that is often very specific to a particular pen or type of pen, but much of its information can also be applied generally to other pens. Learn what is here, extrapolate from it, and apply your new knowledge to the needs of the pen in your hands at any given moment.
