Yes, Maud Cunnington picked it up after it fell over in 1911.
When Keiller came along he decided is was updisde down and turned it over.
In 2003 I pointed out to Mike Pitts that it had a red band around the top indicating that it had been in the ground for a long time. http://archive.thisiswiltshire.co.uk/2003/02/20/163660.html
