There is very little extra information at the United Kingdom War Memorial website. These are my images. The reference is
WEST MARTONUKNIWM Ref: 29721
|Looking towards Lancashire|
There is an excellent link to the history of the soldiers who are inscribed on the memorial here.
Believe it or not. 3 hours later we passed the same spot and the local authority were mowing the grass and giving it a general tidy up.
