Early 911 S Identification Plate

My 1971 S identification plate is different from my 1971 T ident plate. Oh I know that sounds stupid but aside from the T and S designations, there is an additional line at the bottom of the plate. First there is the zul.Gesamtgewicht kg 1400 on both plates. The T plate has an additional line below the zul.Gesamtgewicht kg 1400. zul.Zuggewicht kg 2000. The S plate does not have this. It is a smaller plate. Is this normal/O.K ?

Thanks

is this the id plate in the engine compartment?

It is the id plate that is riveted in on the front panel (trunk). Interesting, what plate goes in the engine compartment ?
