Steven- Why does it appear that the Campy Company used the exact same serial numbers to identify these same two derailluers? Cheers, Dave Anderson in Cut Banl MT

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.
