"1750" badge on 1971 Spider
The rear, left-side badge on a 1971 Spider is usually "INIEZIONE," but I occasionally see a "1750" badge instead. Does anyone know why this is? USA vs. Euro version? Did Alfa run out of 1750 badges at some point and figure it wasn't worth manufacturing more since the 1972 would be a 2000? Is this a stupid rookie question (haha)? Just curious.
