I am interested in you opinion of why some, but not all, have the appearance of a light leak on the film.
Thank you for your reply,

What order were the pictures taken? If the light leak happened on the first one, two, or three images—but not on the last three, then I’d look at the loading procedure.
The paper backing must stay tight with the ends of the film spool. If it comes loose then light can get in at a small gap, but that only affects the first few frames, as the wrappings of paper will protect the inner negatives.
If the light affects the last two or three images, then it is likely from loose paper/film wrapping when unloading the camera, or possible damage before or during processing.
If these light leaks happen on mid roll then you can probably rule out loading problems.
If you removed the lens at some time while the camera was loaded, or walked around in sunny areas for a while with no lens cap and the darkslide removed, then check for a bad seal on the camera’s mirror box. I’d particularly examine any cushioning where the bottom of the mirror rests. While checking that area, look for any shiny areas.
Strong sunlight coming through an open lens can sometimes bounce around inside the camera, reflect off shiny wear spots, or get past worn foam or felt seals.
Last I’d check the film holder for light leaks. If it was not removed for loading, then check the darkslide seals. Usually leaks from the darkslide show up on the edge of the image, not the top, though. But it is possible if there is damage to the seal in the middle of the frame and the back is off the camera. When it is on the camera, unless the camera has a light leak, the darkslide area is covered by the camera.
Since the problem shows at the top of your image, look at the darkslide track along the bottom side of the holder.
