I-RVEG —

What is it? As I'm not an expert on aircraft identification, I-RVEG and MB32 tells me nothing. More information would be greatly appreciated.

It's a Macchi trainer

The Aermacchi or Macchi MB-326 is a light military jet trainer designed and produced by the Italian aircraft manufacter Aermacchi. It is one of the most commercially successful aircraft of its type, being bought by more than 10 countries and produced under licence in Australia, Brazil and South Africa. (Wikipedia)

In South Africa, I think it was called an Impala.

@theo is you enter the ICAO type code M326, your photo will be correctly listed as a Macchi MB-326.

G Zorbas, yes you are correct, it was called the Impala in South Africa. Seen many of those in the 60's and 70's.

The aircraft has the insignia of the "VI Stormo" of the Italian Air Force, based in Ghedi, the "Red Devils".
