I think we can both take credit for the wheel well comments/observations.
The only independent reference photo I have of the American Roadster has a more open well...but, unlike the awkward circular roundness of the red example, it has a 'flattened' top to the radius...visually more attractive within the rounded smooth blending bump of the fender.
And my 'ooops'.
The initial Porsche importer was MAX Hoffman...not his cousin Hans
