Wow, that car is gorgeous, don't think I've ever seen that color combo even when they were new.

I'm sure the 1st thing on the BS was gas, which is kinda funny since they'd all have SOME fuel in them to move, load & unload.
Haven't seen that on my BS. N/C I would interpret as No Charge...

As for "omit wax", that kinda makes sense, if something was sprayed on the cars before transport and this car was being picked up from the plant.
Whether a shipping wax or coating was applied back then, I don't know.

It'll be interesting to hear from someone with plant experience...
