Now you have me confused. I admit that I do not specialise in veteran cars, so I can only use information that's available to me. (I recognised the car because I had selected another model of that marque for a puzzle of my own only yesterday!)
I thought you would question the model I put in my answer, because that car looks a lot smaller than 11CV. It is registered P6471 and I have found two other photos of it on the internet, and both claim it is a La Ponette - one site is a well-known one run by a member of AP, and the other is a French-language site for enthusiasts. The latter is the one that states that it is an 11CV, but I think that model is actually an 8CV, built from 1909 to 1911. Georgano says that it is 827cc, but the Wikipedia site claims 697cc.
Now you tell me that it's Italian! There's no mention in Georgano, but I wonder whether it was also made in Italy under licence?
