Thanks for bringing this article to our attention. Tri-x has a unique palette, grain, and highlight preservation capability. It came along at the right moment in history, that moment being at least fifty years in duration.
I'm not sure that there are any papers left to bring out the best in Tri-x. I've since switched to Delta films and Ilford paper.
It's the first article I've seen that acknowledges that Tr-X was introduced before 1954, although it was 1938/9 not 1940 and made in the US, Kodak Ltd UK and it's Hungarian subsidiary which later became Forte.
