Just to expand on Laurie's comment.
Record pivoted/indexed by PSN. Shows:
BETSBAC code (Body, Engine, Transmission, Steering, Brakes, Axle (rear) and air Conditioning). This is all that is on the records from the Vehicle Master Listing that had all the information to create the Broadcast Sheets for each car.
The rest is:
Completion date.
Series
Model
Engine number (as recorded and sent back by dealers) but not always.
Transmission serial number (as per engine number but rare to be there).
Warranty commencement month/year.
Credited selling dealer (better called Cost Centre as this is either dealer or cost centre for internal cars).
Zone Office that placed the order.
As mentioned, the areas where errors occur in in engien number, transmission serial number and to a lesser extend the sale month/year and dealer code, as these are all manual data entry.
Not all cars are there either, primarily as they hadn't been sold, for example when the HZ records were printed on 20/6/78 it was mid series so HEAPS of cars that are not yet sold do not appear on the HZ report. They were in the VML for production but not on the Service/Warranty report as they had not yet activated their warranty. I have examples from all Series though, I have a Broadcast Sheet off an LJ XU1 that isn't on the records. Plus cars destroyed prior to sale are not on there, like the cars burnt in the WA dealer fire (including two HX LE's) and those in a big train smash leaving Pagewood going South. Some of the HDT race cars aren't there either.
