A few years ago at MCACN, there was a panel discussion with a group of former Norwood workers. Someone asked about paperwork. They said 'sequence sheets' [as they called them] were pasted on most sub-assemblies, discarded upon installation. At the last station, cars went through a final-inspection. One of the tasks there was to de-paper the unit, removing and discarding any and all paper work accumulated during final-assembly.
Over the years, I have seen and heard of body & chassis broadcast sheets found and retained by the dealer in Norwood built cars so it did happen. Relative to the over 550,000 1st gens built there, not even 1%.
A bud has a Van Nuys built SS-RS with both copies in excellent condition.
