I will look this weekend and see what I can find. Sometimes with an original car the is so old, it is hard to determine the original finish, but it is usually easy to determine if it was natural of painted.
Do you have the MCA 69-70 judging rules? There is lots of helpful stuff in there along with the AMK fastener guide which is "usually" accurate.
Hey! (Don't know your name) Thanks for your reply regarding the "natural" clips! Can you PLEASE identify any other "natural" hardware that's visible between the radiator and the grill? With a car that's NOT original I kind of fly by the seat of my pants some times.
