These are a roll of PX125, 120, fresh, dev'd in D76 1+1 at normal time, stop and fix in normal fix. I did some rolls of Tri-X in the same stop and fix and made fresh developer from the same jug and those rolls were fine.
Two types of damage seen in the dog and the window pictures: there are no marks on that window, that's all emulsion holes. The marks in the shadows of the dog picture seem to be rubs or clouds in the emulsion. Then a couple of pix of the roll from an angle to see the emulsion damage.

Anyone know what this might be?

thanks.
