Considering that some of the Atlas guys are members here, perhaps if you asked them nicely they could share a photo/drawing of the inspiration....
I'm actually going to drop a line to Cory with a couple notes about the car.
The way it sits now, the car can be mostly correct for all three main variations, but not 100% correct for any. Maybe that's the best way to do it.
My only concern at this point is the application of the 10 stiffener roof. Atlas thought it was important enough to do the tooling for. I just hope they know it was only used the first couple years.
FWIW, we've only seen the 7' door version. The 8' will have a completely different sil since the track is longer. So maybe there are a few surprises that we haven't been told about yet.
