Partly correct. The car is indeed made by "Officine Meccaniche Achille Andreoli & Figli" in Codigoro, Ferrara.
However, based on my information, there are no relations with OM, neither Andreoli was a car dealer.
About the year, it's not really clear even to me, so let's assume 1922 is correct.
To get the point, I still need to know the base and the name.
Not that there is a specific story behind the base-model, and this is the most interesting aspect of this vehicle.
And it also has a name (it's on one of its advertisings).
