No, I don't think so. Please read the rest of the discussion and especially note the fact that the actual negatives do not exhibit an overall higher density along the edges.
I've seen this before, back in the 80's when I worked in photo labs we would occasionally get a roll of 35mm or 126 that had been in Grandads camera for years. This is heat/age related fogging on very outdated film. The fogging starts on the edges and migrates to the center till the entire roll is fogged.
Just as an update, I took another roll of film, a fresh (non expired) roll of Ilford Plus 400 B&W. No issues with this roll, so definitely no leaks nor degradation along the sides of the frames like the previous roll. For this roll I used a yellow filter however and thought I’d get more cloud definition, but I had to bring that out with LR. I’m learning. Pretty happy with the sharpness however.
You do have some vertical streaking that shows up in the sky. Such as sky above the space between the two ship masts, and right side above building. Not certain if that is uneven development, or a scanning issue. Seeing that it may be in the same location on all three shots, I'd guess the scanner needs some cleaning in its calibration area.
