That's a Stronglight 49D if I'm not mistaken. EDIT: Now that you posted the side shot, confirmed, 49D.

Wheels can be replaced and so can cranksets. I recently picked up a PX10 that was a weirdo... Lots of Campy Record (including Super record hubs and Araya red labels) and a Stronglight 99bis crankset, Stronglight Super Record headset... and an Rx100 rear derailleur. Long story short: owners change things. Decals are indicative of something in the latter half of the 70s, 75-78ish, I'm guessing 75-76. Fork is normal for anything PR and under, rear dropouts are correct for something PA or higher. Would be interesting to see the downtube, looks like Simplex Criterium levers.
