I want to show to you this French M78/F1 of "Lègion Etrangère".
Time ago I met a former a ex Italian legionnaire and when he learned that I was a collector gave me a box with pieces of his old equipment, among whom was the helmet, that he had kept as a souvenir.
He told me that with this configuration was the one he had used in combat during the French intervention at Chad in 1983-84; of course I appreciated and I thanked him.
It appears in very good condition and when I clean it, inside I found still red sand, traces of the places where he had been.
The green cover is held in place by a rubber band and behind it's visible the gost left by colored triangle in which the unit number was indicated; inside it's marked: GIAT-ARS 1979.
I did a little research on this war, that actually confirms the use of this configuration, in some image of this video, found in You Tube, are visible helmets like this.
