The 1916 triangular female badge is very familiar but look at the one in the dead centre. It has two brass attachments relating to the dates the munition worker served. I am assuming that this is a) A factory addition to the badge b) done after the conclusion of the war as a type of ‘tribute’ or c) simply made by the owner of the badge.
Does anyone have any ideas.?
