But when I looked at the paper, it seemed to have very little relevance to transient magnetic effects in lead objects.
It took a bit of looking between the two papers, but I think Ridout was using the Maki et al paper to show that the magnetic field would be di-pole.
Not that I fully understand what that means!
I liked the paper a lot, and it gave a far better solution to the flooding explanation which never quite worked, since the wooden coffin in the vault didn't move.
