No problem, gives me an excuse to go check it out!
I think you are correct on a single person assigned to adding specifc documentaion on the sheets. I have have a few baltimore one's from 69-71, and all the notations were done by the same person based on writing style no question.
Purely speculation, but I think this car might have been one of if not the first VN car built with the COPO spolier(05E). It has the Option circled,as to bring attention to the line workers maybe for bolt hole location?. My Bal pilot LS6 has the RPO circled, and hand written below the RPO codes and also circled was "Pilot job 454 c.i." and to the left of that" it'll need wings"
