My GP never had the decal. The way to tell is the dropouts, but it's hard to tell from the pics. GP should have non name in the front and campy in the back. The ones in the pic do look stamped (not forged), but it's hard to tell. Components have been changed for sure. That crank looks newer than the bike, and the rear wheel does not look original. The frame itself doesn't look low end to my eye. I loved my Gran Premio. The paint was cool, the workmanship so-so at best, but the ride was great.
