Based on the license number "MI 166875", this should be the 1950 Ferrari 166 MM Touring Barchetta s/n 0058M, entry #30 at GP in Portugal on 17 June 1951, I think, since it is entry #30. If that is correct, it was driven by owner Eugenio Castellotti and he ended in 7th place.<a rel="nofollow" class="external autonumber" href="http://www.barchetta.cc/english/all.ferraris/detail/0058M.166MM.htm">[1]</a> The driver in this picture would probably be Castellotti, then... if GP Portugal in 1951, it may be at the Circuito da Boavista (guess)
