This is an Italian OM truck, built by FIAT after they acquired OM and then manufactured as an IVECO after IVECO was formed, consisting of the old FIAT, Magirus, Unic and European Ford Truck companies.
These had 6.0, 7.5 or 10 ton gross weights, and the combination of six stud wheels and a large water tank would suggest this is most likely the 75 ton version.
