Kyt, that is a very interesting memorial. Get on to EH about its condition, they may be able to help. Failing that petition the local Bishop. it is up to the Diocese to maintain these things within a churchyard.
Will try and get some shots of my local memorial on Sunday, though I have noticed that the little crosses have already started to be planted in the grass.
Of course that assumes I will remember.
Andy, here's a Gallipoli shot I pinched offline for a local history book.

Nana, the reason they cant just point a steam cleaner is that it would literally destroy the stone work and damage the bronze. its a specialist clean only unfortunately..
