Hi,
Difficult to be certain without seeing the camera but longitudinal scratches like this would point to something like dirt or sand in the camera in the film path. This can also get in the velvet of the filmm cassette causing similiar problems. The cure - cleanliness

Is that with film you develop yourself ? ie: it's not the lab scratching the film loading it into a machine ( I get that with BW c-41 films a lot, to the point thet I've more or less given up on them except for scanning ).

Michael I had the same problem on my last roll. I'm not sure if it's the case but on that roll I remember I actioned the wind lever with too much energy on the last frame, and I could notice how that made the sprockets slip and jump between film sprocket holes (no good!). From there it's very possible that my film moved slightly inside the canonet film pressure 'tongue', leading to scratches similar to yours.

Check if one or more of the sprocket holes on your film is damaged or bent, that could be an evidence...
