Charlie, the engine bay has never been messed with. Actually, the whole car has never been messed with. The only thing that I can see they added was an under dash tach and there is a gold colored box mounted on the fire wall. Besides that nothing appears to have been done to the car. The car is being sold by the original owners. I'm kicking myself for not getting better photos.
Yes, the paint is original from what I was told and it looks like it. The only area was a small area on the front header panel just ahead of the hood that was dinged back in the '70's that they had fixed. The paint is really very nice for its age.
Thanks,
Mike
