French greatcoat, I am wondring if it is WW2 army issue.it folds up at the back and front like the WW1 coats, half silk/rayon lined, very pointed collars.It is marked inside Lyon and the date looks like 3/4?, which would make it wartime vintage, but date is unclear, so for all I know could be 3/5?French greatcoat, is it WW2French greatcoat, is it WW2French greatcoat, is it WW2French greatcoat, is it WW2.Insignia unfortunately removed from collars
