those aren't fake, rather R&D mockups.. notice the dates of the photos, 2 years prior to that body style release
as far as the split window, notice the offset margin at center where RH overlaps LH.. probably was a working model..
also notice barn door hinges or dummies on left side of gate and hatch that don't belong..
maybe working on two way lower gate and hatch like the old wagons??
who knows what ideas went around the floor during development, all we do know is what was eventually released
