Bah! Looks like I'll have to make do with the <a href="http://www.themodernantiquarian.com/browse.php?site_id=3349">Claremont Road stone thingy</a> and the cross-sectioned tumulus over the road...

Actually - I have walked past and peered into the tumulus on many occasions, but just presumed it was a display case with a skellington in it... I'll look with more interest next time...
