Stig,
For your information:
Italian Aviation Units in the First World War: Volume 1
https://www.amazon.co.uk/dp/19532019...s%2C138&sr=8-3
The first of five volumes apparently.Based on,or in fact even a translation of, Gentilli and Varriale's I Reparti dell'aviazione Italiane nella Grande Guerra, which I think you already own. However, that book numbers 491 pages including the index whereas this first volume has 262.
TBH my trust in Aeronaut publishing is not particularly pronounced and not only due to the Davilla volumes.If you or anyone else decides to go ahead and purchase this volume I'd be very interested in your impressions as in the Who's words personally I 'Won't Get Fooled Again'. A pity it has come to this.
Regards,
Clint
