The camera is Olympus OM2n. Light seals of the camera are OK.
It was developed by a lab - snapshotphotos.co.uk - they always provided me very good and consistent results in case of B&W processing.
I double-checked the negative, the last four image is wrong - it's happening it's the the last strip, as the negative is cut into strips.
The shot was taken on Inishbofin, a small Irish island west from the mainland. It was a very lucky day, sunshine, nice weather and beautiful shots, my first image in this gallery was also shoot that day.
Mike, "Looks like a light leak from the film canister as the banding corresponds to the sprocket holes in 35mm film." - I'm just wondering that factory Ilford cannisters can leak?
