 Polytoner is discontinued. However a similar toner can be
made by mixing Kodak Rapid Selenium Toner and Kodak Brown
Toner along with some alkali. I have formulas calling for
carbonate and others for Kodalk. Check the archives of the
Pure-Silver list or the rec.photo.darkroom group via Google
Groups. I will repost here if there is intrest but the
formulas should be available from the internet.
   Agfa Viradon, which was a combination toner until
recently, is now a polysulfide toner.
