musings on iron railings

Derek writes: We begun cutting the Churchyard grass this week, probably the earliest we have started. Not for the first time I mused over why
the metal railings were left around only one of the box tombs, many of the others had railings originally but were removed during WW 2 to be melted down for the war effort.
There must be a good story to be told, any ideas ? I read that only 26% of all the iron collected was turned into munitions, but the collecting helped to unify the war effort.
