3021, a great car, probably didn't have a sign of any 1966 Shelby factory paint after it's shunt, color change then back to gold.
3047 hasn't had a shunt and has 90% of it's 1966Shelby factory paint after the de-paint.
I am not aware of another S/C with any original Shelby factory paint.
Besides that, the original
oil cooler, diff cooler and original vinyl seats to mention a few, are pretty amazing.
My personal definition of original is what the car currently has that it was born with as opposed to what it was repaired or restored with.
3047 was never restored. Just maintained to continue to run which it did up until a few years ago. I drove it from Maryland to New Jersey and it didn't miss a beat.
