With the Civil Defence services being stood down in May 1945, a large number of groups had 'stand down' group photographs taken. These provide a wealth of information on the insignia in use at the close of hostilities. The below photo shows a number of men that appear to be all in junior supervisory roles. The gentleman far left has the star above the three rank chevrons and five war service chevrons. There are a smattering of first aid badges on the right breast pockets but I cannot discern the area marking title (it looks to be quite short in length). As usual not everyone had a lanyard. A good number here are veterans of the first world war.
