There is a Macchi 205 in a museum in Italy that has recently undergone a massive restoration,there was another 205V serial MM91818 at the technical school in Udine in the 70's.
At Vigna-De-Valle near Rome is the resoration centre for the national museum and they have a 200 Saetta and a 202 Folgore which was in a pretty sorry state when I saw it back in 78.
