Needless to say happy to remove if the consensus of opinion is 'no', but happened to (literally) chance across this slab just c25 paces approx south-east of the Turin Hill summit stile. There are numerous conglomerate slabs in the area (with cavities where the pebble had been obviously dislodged), but this one looked very, very different to my untrained eye.

The OS ref I've given is approximate.
