I have looked at the photos and the derailleurs that I have at home and I believe that the difference between the Valentino and the Gran Sport front derailleurs can be summarized as follows:

The Gran Sport (GS) has a top-fixed derailleur cage instead of front-fix of the Valentino. The cage of GS is screwed together in the back, whereas the Valntino is riveted. The Campagnolo haut-relief name on the rear of the derailleur is much heavier and cleanly printed on the GS. The chrome plating on the GS front plate, cage and front-plate fixation screws seems to be heavier and shinier than that used on the Valentino. The arm where the cable fixation nut seems to be somewhat lower on the GS than the Valentino and lastly, the cable fixation system on the GS uses a perforated screw and bolt system whereas the Valentino uses a threaded arm with cable clamp.
