Thanks, LCJUTILA.
I'm reasonably (95%) sure that the paint is the original, as I got the car from the second owner who had it 30+ years (22 stored) and he had never painted it. Also, when I rubbed out the (oxidized) Viper Red paint, it matches the paint in the trunk, engine compartment and under interior panels really well. Also, where I have sanded off the paint to make dent repairs, the paint didn't seem abnormally thick (my old '56 Chevy 210 had SIX different paint jobs hiding under the topcoat!) But, judging from the amount of paint that came off when I rubbed out a small area, I going to go with it being a lacquer job.
