We tried to look for this particular model in the literature at our disposal but we knew from the beginning that it would be a difficult challenge.
The reason is simple: in the 20s and 30s luxury cars (this Fiat falls into this category, although it might sound strange) were almost always built on the basis of specific requests from the customer so, actually, there were no two identical cars even if built from the same bodyshop, and even if as big as Viotti.
This car, with its elegant color combination, is said to be the only one in the country (and we do not find it hard to believe it) but apart from that there is no description. What we see is a car in fair conditions, which does not seem to have been modified over the years, certainly we can not know if the colors are original but we are almost sure that the steering wheel was taken from a more recent Fiat, the only thing sure is that, once restored, this car will be splendid.
