"Do you reckon this photo from the Soukos Designs web site is the Kinnerton Court Stone II?"

I really couldn't say, have never seen it, I need to get back there soon now that the winter is coming, much better views etc and less grubbing around in foliage :-)

Interesting point about the area, 'Bache Hill' (sighted by the four stones) used to be called 'Badland' or 'Badlands' up until recently in history. Still need to track down old name of Whible. I'm still amazed at the lack of research done in the Vale of Radnor, it's such a mindblowing place.
