I did it today, the sign that contains the sheet that gives you the info has been removed.  However, despite that, Dave did allow me to claim it as I was able to provide the answers with out the sign.
I did go up to the K & Q stones and take a picture, I took a picture of the stone by the barrier and a couple more at Cherry Tree Quarry just in case there were any questions.  It was a lovely morning and a pleasure to be on the hill...
What you do is up to you though
