This was called Conch in the 1982 guide! In that book, Ruf was the corner to the left (now no longer listed, but claimed on UKC as Heaven Corner).

Start on the left of the slab next to Agnostic's Arete, climb up for about 3 meters and then make an unprotected tricky step right (crux) almost into conch. Gear awaits above!
