1963 Ferrari 250 GTO s/n 4491GT at Monza on 8 September 1963, driven by its first owner David Piper from England, to a 2nd place in its class and 4th place overhaul.<a rel="nofollow" class="external autonumber" href="http://www.barchetta.cc/english/all.ferraris/detail/4491gt.250gto.htm">[1]</a> A guess might be that David Piper is the driver. He had bought this car in June that very same year, but sold it late 1964. The yellow AGIP advertisement in the background suggests this is in Italy and not in UK, where he had raced with #44 earlier in 1963.
