That's all the information that's in there.
You can pay PCNA (Porsche Cars North America) a C-note or it might be more now for a "Certificate of Authenticity". It will probably tell you the original engine number, but I'm not sure if all of them do. And the certificates are transcribed from hand-written notes and often enough have errors, particularly in the option codes associated with a particular VIN.
...Then again, as a 1970 914-4, we know that this would originally have come with a W-code 1.7 liter engine with D-jetronic fuel injection.
