I can't find the account of the second carved head, here, and have had a good look. The sites are pretty jumbled up - could be separated as collections of moors ? Smithills Moor, Rivington Moor, Anglezarke Moor ? Can we nae all the moors ?

An interesting legislative link here ( http://www.publications.parliament.uk/pa/cm199900/cmselect/cmcumeds/371/371ap72.htm ).
