In reply to Steve Clegg:
Hmm. We climbed it yesterday, and there was no sign that it had been climbed in years! The "impeccable rock" mentioned may well exist, but it's hidden under a layer of moss (though we trundled one large hold on the first pitch). There were the remains of a
very rusty nut just below the crux of pitch 2, and the finishing holds of the crux itself had to be excavated from under 4 inches (no exaggeration) of moss. Even then it was technically much harder than anything on Bowfell Buttress (which we did before).
In its current state probably something like HS/VS 4b, might be HS 4a if ever clean. Certainly not worth any stars at the moment. I doubt it was checked for the new guide, possibly not for the previous one either!
