Italian Air Force book

[spanienflieger]

I am thinking about purchasing a copy of Giuseppe Valle's book "Uomini nei cieli - Storia dell'Aeronautica Italiana".

There are two editions of the book, 1958 and 1981. The later is cheaper (30 Euro instead of 50) and has a lot more pages, so I suppose that it covers also the 1958-1981 era. I am interested only in the Italian Air Force intervention in the Spanish Civil war, so I would like to know if that part is the same in both editions.

Thanks in advance
