Lots of consistent data.
Here's the updated compilation. 67 has a calendar week code. 16 D 7 would be the 16th week of 67, day shift. 40 6N would be 40th week of 66, night shift.
The format changed in 68 and 69 to have the week counted from the beginning of the model year. The extended 69 model year used tanks dated for the 70 model year.
LOS and NOR data is intermixed and shows the same pattern.

Good point, but since we don't know where the other 06A cars fit in, I'll just leave it as-is. :)
Thanks!
