In this pdf file on the kodak website (on the new Tmax400) are some photos by Salgado, including the film & equipment he apparently used.

interesting that also on the Kodak site, here:
KODAK PROFESSIONAL TRI-X Films
he used a mamiya RZ 67 for the same picture, as is the brochure is stated he used a leicaM and 35mm lens. (the ratio of the picture does not look like 6x7...)
here's another link with some nice pictures on a project he did for illy coffee:
