The faces of the stones have been blown by rust expansion.  In some cases the staples that connect the blocks are being removed and replaced.  Where this is not desirable Fertan is being used to convert and remove the rust, providing a stable and long lasting base for overcoating.  Many thanks to Nick Morrisey of Cameron UK for his time and attention during my visit.
