I've seen photos of this model claimed to be a 1900 or a Giulietta depending on the source...
I think 1900 should be the best hypotesis, because some of the styling cues of the car are really similar to the Gazzella of the same coachbuilder, which is something like a simplified version of the model...
The design is also much more from the early '50s then from the era of the Giulietta... but it's just my opinion...
In my book (still w.i.p.) about 1900 "fuoriserie" I would insert this model explaining the doubts about the identification...
