Undercoating would be on the broadcast sheet and not the tag.
Some codes do not appear on the tags at certain parts of the model year, then they do, then they do not. Some change from day to day. Do not look for that type of info to be posted anytime at all by me, it is one of the things I use to spot fake tags for people.
As far as the D34 / D32, the information posted in the scans is not compete, keep that in mind as well.
