I bought a box of Ansco chemistry off the internet, the cans were packed in magazines pages dated 1954. I have a number of quart sizes cans of Normadol, and gallon sizes of Permadol, and D 45. The Normadol cans have keys for opening, but the gallon size look like paint cans with a pry open lid so I dont know how well any of this has held up over the past 1/2 century. I also have some foil packets of Pinakrytol Green DeSensitiation mix for use when developing by inpection.
