Bernard, I saw this, and thought of you! It may be of interest to you. http://news.bbc.co.uk/1/hi/magazine/4997470.stm. If you can’t catch the link, look on BBC News Magazine and search for ‘London’s Heart of Stone.’ It is about the London Stone, saved from destruction by a builder! Apparently, it has sword marks across the top of it!? Barb Ford
