I've got one of these stones at home - it's been buried and the carvings are, consequently, fresh. In these cupmarks, at the base, I can see pick marks. I could photograph them, I suppose. I offered to lend this stone - which is beyond what the HSE would term 'portable' - to Aron at the Uni., for six weeks. He said "the lift only goes to the third floor". I was going to show you the stone if you'd got through about half - say twenty - of the Knarsdale carved stones. It's my good luck charm and radiates a phenomenal spooky aura. (There's a picture of it on the Thornhope page).
I'd better go and catch me bus. I've got one of these natural oval-hollowed stone to photograph ...
