I don't know what model this is. It lives in New York, I believe. Image Unavailable, Please Login Image Unavailable, Please Login
I agree the cars shown in the two Stanford Library archives do not seem to be related to the "factory" 412 cabriolet. The fuel trap location on these pictures is for a standard 400/412.
