I think the hubs are the Tipo model.
That entire rear derailleur arrangement is messed up. Derailleur on a claw-foot derailleur hanger attached with a bolt at the derailleur mounting hole in a Campy drop out instead of around the axle. Spooled excess cables? Cut them to size and cap them.
I would correctly attach the derailleur to the dropout. If the threading is incompatible, get a derailleur pair that works - Campy NR comes to mind.
Your link to Velobase does not work for me and will probably not work for any non-member.
