Vin code vs first registration

Can You show us the registration document?

In Austria we have a so-called 'Typenschein' - and I know some cases, where the 'Typenschein' does not match the car. Mostly because the 'real' car has no valid papers and a 'Typenschein' of another similar car was 'bought', to registrate the car. There exists a 'black market' for such documents..
But I think such things are common with very old cars.
