Determine age of found Tri-X Pan 400
I found a roll of Tri-x pan film, ASA 400, and I want to shoot it. However I've never exposed this kind of film, and I have no idea how old the roll is.
See the picture below; can anyone estimate how old it might be by the print/design on the roll? It doesn't have any DX coding on it.
I've also never shot black and white before...so assuming I can figure out roughly how old it is, how would I go about adjusting for exposure? Pretty much all of my experience is in color negative films.
