Well, a bit more info to put on the table of the jigsaw!
The supposed drop zone on the map I have was not a drop zone BUT there were 3 in the area, the main one being near Bouin near to the Ile Noirmutier.
There were various arms caches in that area, many found by the Germans and French police through informants. The people caught hiding arms were sent to Auschwitz.
Because of this problem my friends cousin went out and secretly, without telling anyone, moved various caches to a a place called Apremont before they could fall in to enemy hands. It is possible that the rifle is from these arms.
The details I gave her are presently with her family in the area so I hope for more detailed information later on.
