I agree that it is gracious offer but I'm going to keep the paper. It does trouble me to be so stingy, but I have found a good use for it. I bought a lot of paper that included the Azo and some Velox that was dated between 1956 and 1970. It turns out that all of the paper is good and the Azo is not the same as it is now though I don't have any new grade 4 with which to compare it. Maybe someone out there knows a little about the Velox. When I did a search all I found was that it was used to make postcards and and that the name velox used to synonimous with a proof or copy. Is it also a chloride paper?
