All of the Italian sports racers used some type of hand-made aluminum mirrors. These are made from the pattern used on the mid-fifties Ferraris and Maseratis through the early 1960s. The correct Italian style mirrors can be distinguished by a little spring clip that is used to retain the glass. Sometimes they were painted but often they were left with a brushed aluminum finish. There are good photos of these mirrors on the 335S racers on pgs. 92 and 94 of the beautiful book A Champion’s View by Phil Hill. 1950s Style Racing Mirror.
