1969 Norwood Trim tag date anomaly's

Excellent post, thank you!

Do any of the workers recall exactly when (what day of the week) the production week designation advanced to the next letter? And how long did the code for the final production week of a calendar month (such as 02D, or 03D or 03E) continue to be used into the first few days of the next calendar month?

Based on observed tags from Chevelle plants (not Norwood), it appears to me that they did not advance the week designation on the 1st day of a given calendar month, unless that happened also to be the first day of the new production week. For example, I have a 67 Baltimore Chevelle that has a broadcast date printed on the trim card of 12/1/66 (which was a Thursday), but it has an 11E Body Plate.

And that would make sense as long as the first day of the production week was not Thursday. For example, if Wed Nov 30, 1966 was the first day of the E week, you would not expect the plant to reprogram everything on the 30th (to 11E) and then turn right around and reset it all again the very next day to 12A.

That would also explain why it seems like you see far less A tags than D and E tags, if most of the first week of a calendar month is still being coded as D or E of the prior month. Then I would guess they would jump straight to B when the next production week began.
That is just a guess, but it is almost the only way to explain why (at least with Chevelle plants) there are so many months with an E week found on Plates.

If you pick any given weekday as the hypothetical "first day" of each production week, and carry that day all the way across the entire 1965-1967 calendars, you cannot find a weekday that will yield a 5th "E" week in every month that there are E tags existing for. So there HAD to be something odd about how they handled the first few days of each month (unless the first day of the calendar month happened to also fall on the first day of the new production week, which would get an "A" designation).

Thanks again for your efforts! Jeff
