Scanned photos of my father in law climbing in 1955/56, he thinks the climb is somewhere on kinder. The Group shot was taken by FiL, he believes the climber on the far left was one of the great and good of the time. I would much appreciate your help in identifying the route and the climbers pictured.

Hiker's Crack

Yup, Hiker's Crack, Upper Tor, Kinder South. S 4a these days, so probably Diff (Just) when the photos was taken.
