The car looks great. If you have pictures of any paperwork that you have, and the car's ID tags, that would be fun to see. Some people get really caught up in the numbers, and as you can see, there are still open questions about how the cars were built and how they got distributed around the US. Even with the paperwork there will probably still be arguments about whether it's real or not, what "model year" it is, what "series" to call it, whether Bob Sharp touched it or not. Good stuff. See if you can find a Bob Sharp fingerprint somewhere on it.
Remember also that anything original to when the car was built might add more value than being shiny and clean. Patina, provenance, history, whatever. I wasn't kidding about the fingerprint.
