I think Alex is on the right track.

1. That does seem to be a Bosch trafficator, an old one as seen below.
2. The cowl and windscreen are not "Jeep" but rather some sort of passenger or light commercial vehicle front end.
3. The front and rear upholstery is leather or leatherette and the rear seat is a full length bench seat, not the short Jeep one.
4. The top/hood folding mechanism does not resemble a Jeep.
5. The only thing "Jeep" about the photo is the small portion of body and the grab handle is in the right place and the fender/mudguard cutout looks proper.

Probably a "bitsa" assembled post war I would imagine.
