I haven't checked in here in awhile (been busy working on the truck!) But this is fascinating info...It's a niche area of knowledge for sure, but it seems that these codes for these years are info that is on the verge of being lost if some of us don't discover their specifics. It wouldn't be the end of the world, but these little details and reasons for things like extra letters and whatnot just seem so interesting.

I'm not sure i'd know how to decode those invoices, but i'd try if no one else wanted to. Knowing that this info would be of little use in the real world really wouldn't deter me from wanted to thoroughly understand them, if for no other reason than saving the information, and being able to contribute when someone was repopping a decal and wanted to know, for sure, what the right codes were and the extra letters.
