Do take into account that some enlisted in WW2 were colour blind ! Not a joke….with a push for recruits there were aspects overlooked which seem odd today, we even screened people applying for an airfield driving permit with test cards in the 1970s..
as for the subject, brilliant, and neat to see mentions of some of my fellow AAA researchers. An aspect of aviation archaeology overlooked when critics sound off .is that, fabric samples can be found especially in damp peaty places and they can help with research.
