Marazzini Ernesto (S.P.A) is the name of the company who made it. They are/were based in Parabiago near Milan in Italy. They would likely have used a commercially avaliable engine such as Briggs & Stratton but more likely an Italian engine. If you can identify the engine then that makes the spares issue easier. Parts like carburettors tend to come from companies such as Zama and are easy to repair or replace.
I would think that they are much more common in Italy so a search on Italian eBay might give you some idea of second hand prices.
