MX5 Seats

Can anyone identify which model these seats are from, I think they are from a mk1, thanks.

Look like Eunos NA one piece/tombstone seats to me but I don't see any speaker vents. Although there might be a zipper there in the headrest.

Early UK Mk1 seats were the same shape and rarely had the headrest speakers.
