That's a Valentino not a Gran Sport. They are very similar but have two differences:
- Where the shaft exits the body there is a protrusion or collar on the Valentino, none on the GS
- The cage has two bolt holes on the sides for attachment to the shaft on the Valentino, only one on the top on the Gran Sport.
According to Velobase the Valentino was from 1968 into the 80s.
