A smiling face after a serious rear-end impact. Avion Voisin?

The marks on the side of the front wing and tyre could indicate that the car was 'rolled' and ended up in a field!

If it spun off the road and went backward through a hedge - and rolled over the back of the body at the same time - it could explain the damage being mainly confined to the rar of the car.

Suggestion only but worth considering.

I'm agree with precedent replies, Hotchkiss AM2/AM80.

An intriguing picture. Everyone seems to think its a factory-made Hotchkiss from about 1930, and I agree. But the accident? It appears the car is still in the place it happened: off road, in isolated, scrubby heathland. The blow was struck downward from the near side, across the back seat, smashing the body, springs, etc. into the ground. That is why I think the car still in the place where the incident happened. The bludgeoning instrument (a large pole dropped by a crane?) has been removed. Now, why would a car be smashed with a pole in the middle of nowhere? A: some nefarious activity. Either one party got suckered to a place where their car was deliberately smashed in front of them by a crane with a large log, or the car was take to the site after theft or forced appropriation. The gentleman is a senior member of the Gendarmerie.

Pure guess-work, of course.

Hotchkiss

Clearly not a Voisin, but an early 1930s Hotchkiss. AM2 model I think.

Hotchkiss AM80

Oh, no !
Probably an Hotchkiss AM 2/AM 80
