[Unreal]

If I read correctly, the production month is not in the code, it comes from the build date on the tag. But since the production month and calender month may not correlate, an early production day on the scheduling number might very well relate to a 4D production date on the tag.

So H 090 would mean the 90th (090) car of the 8th (H) day of whatever month is on the tag. Theoretically there should be an H090 for each production month.
Do I understand correctly?
