Good question. I don’t know the answer. But I think the sequence number includes all models. I have noticed that the stamping of some serial numbers is different front to back: the characters for assembly plant, year, series and month may be larger or different font than the sequence numbers. Example: 21HS-I 4465. Have others noticed this? That’s one reason I think the sequence number includes all models.
