Maserati 4CL Streamliner at 1939 Tripoli GP on 7 May 1939, driven by Luigi Villoresi, who may be sitting in the car (or not). The car failed a couple of times, and was soon changed into regular 4CL after the race.<a rel="nofollow" class="external autonumber" href="http://www.kolumbus.fi/leif.snellman/gp392.htm">[1]</a>
