Spots and marks on film after processing

[Santaji]

I recently got a roll of Arista Premium 400 black and white film developed from a local lab. I had shot the roll about 6 months ago and it had been stored in the fridge since. When I checked the scans I noticed that some of the images had marks and spots on them. These are visible on the negatives also.

I have attached some pictures of the negatives and the scans of some of the affected images. Anybody have any idea what could have caused the issue?

Also, I don’t know if this is related to the marks on the negatives, but I remember that the film advance felt a little jammed towards the end of the roll. Sounded like the film was being forced to advance. Rewinding the roll at the end didn’t feel as smooth as usual either.

The marks in the images look like drying marks and dirt. Seems unlikely for a good lab, but can happen. The black lines at the edges near the sprocket holes might be "cinch marks", but I'm not sure. Let's see what other think.

I see three things: spots, dirt and development lines. You talked about the first two. Notice the dark line from frame to frame on the negative. I suggest that you have a CLA for the camera, filter your chemicals for debris, use PhotoFlo or an equivalent when processing and never use a squeegee.
