Chris,
it's the third generation (if you don't count the prototypes) of the Gran Sport introduced 1953. The closed C appeared 1956 AFAIK.

Hello,
Is there a site which has photos of all the different Gran Sport derailleurs? I am trying to determine which version I have. It has the cable barrell adj., closed C on the front, open C on the back. It does not have holes in the pulleys.
Thanks,
