Kodak Polycontrast Filter Kit with HolderThis is a complete Kodak Polycontrast filter set, with seven 3x3" mounted filters from grades 1 to 4 in half stop increments. Yes, these are compatible with Ilford Multigrade papers: they may not produce the exact same contrast as an equivalent grade Ilford filter, but they will definitely do the job. In excellent condition, with plastic case, original box, exposure calculator, and filter holder for use on enlargers that don't have a built in filter
