We had a mystery car in December 2016 and it looks like it is time to solve the suspense and undo the tension by deveiling the car.
The car is indeed a Bentley, a 1964 S3 Mulliner Park-Ward with a Norwegian accent.
The Norwegian accent derives from the designer: Vilhelm Koren, a Norwegian. The story is that Koren got involved in racing, just after WW2. He designed a body for an Alfa Romeo and on this basis the London Academy of Industrial design accepted him as a student. He graduated in 1957, with a gold medal. Rolls-Royce hired him and he remained there until 1961. The S3 Continental appeared in 1962, notable for its headlamps, a designed that avoid a stacked Alvis-style set up yet which accomodated the four reflectors by angling them in the space between the wing and grille.
After his stint at Rolls, Koren went on to teaching furniture design. His was a bright but short career in car design and I have no insight on why he opted to leave that branch given his long-standing interest in cars and his apparent talent for the genre.
A short obituary is here and a garbled version here. The second link implies Koren went from designing the Alfa racing car directly to RR. I’ll translate the Aftenpost article soon as Koren’s life story is quite unusual.
