As I mentioned in my fieldnotes (http://www.themodernantiquarian.com/browse.php?site_id=1500) I parked pretty much on the button for the grid ref, but despite strolling around for half an hour or so, I drew a blank.
Ah yes. I suppose I should be quizzing (the delightfully named) GuttBucket. I wonder where he got the information (assuming that the afore mentioned person is in fact male).
It's a shame that Mr Bucket didn't post any photos up.
