I found a possible cup-marked portable stone recently, and last night the Man Stan himself came to inspect it, and declared it Most Likely!
I found it on a beach on Lindesfarne, and lugged it a mile back to the car, as there was no way I was leaving it there. He reckoned it may have been washed there from Scotland...!
Will post more details on TMA soon.

PS Thanks to some people on here who I have asked stupid questions to, I was being a bit mysterious(sorry!)
