Mapping Center Answer:

You are working with a system of local Cassini-Soldner coordinate systems that total 849 origins. What you need are the geographic transform parameters for the local Italian Cadastre of the Lodi District on the Genova Datum (there are two of them - Genova 1874 and Genova 1908) to a datum that is more common. The IGM (Istituto Geografico Militare) or the local Lodi district cadastre office may be able to supply those parameters at this time.
