Webbster, (forgot your first name, sorry,

)
If this is an American car, then yes, they are most likely original.
But since you are importing it to Europe, and absolutely nobody likes those sugarscoops here, you should change them into H4's. (value of the vehicle will not decrease because you did not keep it original, don't worry.) Even in the states, a lot of Porsche owners change to H4. (same goes for those wiiiiide bumperettes...)
Try to find a nice used set, they're out there, and choose between a chrome ring or one painted in body color. (I would say bodycolor, since you have no chrome anywhere else on the vehicle)
