After seeing pictures, I'm questioning if it's a Grand Prix. It's definitely an Atala, as it says on the front tube, but it looks slightly different. Definitely not complaining if it's not, it was free. It has stamped dropouts, Weinmann brakes, a Shimano 600 front derailleur, a Maxy crankset, a Suntour rear derailleur, and Campy downtube shifters. Couldn't tell who made the brake levers, but the hoods are all brown and nasty looking. It's seen better days. My plan was to wire brush all the old paint and stickers off (they're all unreadable anyway).
