sanking said:Michael has made you a better offer than I can make but I would certainly like to test the film. Just yesterday I did a comparison test of some modern AZO #2 and #3 papers with some AZO #2 and #3 from 1946. This evening I will run the curves and eventually post them in the technical gallery. I was pretty much stunned at how good the old paper was. I would love to be able to include the 1925 paper in the comparison. If interested send me a PM at firstname.lastname@example.org.
