AH! That makes a big difference, I'd buy this in a heartbeat if it fit me: a classic Italian frame with very desirable (and sort of rare) French components. I can't see what the brakes are, but they sure ain't the Mafac Racer centerpulls that I had imagined. They do have external nuts, which I am a little surprised by, but that's a very minor point. Looks like it could stand a good cleaning and rust spot touch-up, but should be a wonderful ride.
Edit: I looked again and think the rear brake shows a Modolo rubber bumpber, now think these may be mid-grade Modolo brakes like Speedy or Flash. Not their best stoppers, but easy enough to replace them with some higher-grade Modolos, ideally some that Modolo branded for Mavic, it would complete the gruppo. BTW, I think that Simplex also produced those retrofriction shifters under contract and branded them as Mavics, too.
