Kodak Polycontrast Filters(used in box w/ holder)
found these in a box with some other darkroom equipment I'll be listing here shortly.
filters are in great shape, comes complete in box w/ lid, as well as the under-the-lens filter holder.
optimized for kodak b/w papers, but can be used on ilford/other brands as well, just a tad different on the rating scale of contrast grades.
$25 OBO shipped in the USA, 50/50 on int'l shipping(incl. Canada)
paypal please, you pay the fees(mark as a "gift").
