The Fiat RA.1050 RC-58 (DB 605) powerplant installed in the Reggiane Re.2005 airframes had a characteristic feature, its supercharger air intake mounted on the port side fuselage. In the kit, this part has to be modelled using two halves, now you are offered with a single-piece item, all you need to do is cut away the casting block and use instead of the styrene intake. It also offers much finer surface detail.
