I wrote this before I came upon some of the explanations linked, but left this question standing because of my intrigue that nothing seemed to have been done against more noticeable use of FAG in some cemetery articles.  Thank you for your explanations.  To date I have come across accounts of his death in Shropshire newspaper articles and a book on Shropshire war memorials (he is commemorated in Church Stretton) but they lack the detail the FAG had.
