The year must be 1932 or 1933, because then Rally ceased production. It went under the name of Rally 1500.
I had this model taken into consideration very early, since most details fitted (flared fenders, louvered hood, chrome bar between the front wings, RHD), but the only picture of the Rally 8 CV I have, shows a convertible and that is very low-slung and sleek looking. The pictured car, although being a coupe, looks more like a two-door sedan, which led me to the thought that it can't be a Rally.
