Thanks and a good source that I did not know about.
By the way the link for the above airmen is:
http://augusto.digitpa.gov.it/gazzet.../id/1941274_P1
And the post above is citing airmen being awarded "Medaglia d'Argento", the following page continues with awards of "Medaglia di Bronzo" and cites one more airman with date 15 Octobere 1940 and place Ras el Ara:
Aviere Ottavio Coronati.
There are also several names linked to Aden 13 October 1940, and so I will probably be able to identify the two men of Gheradini crew killed on this date.
The link for Gheradini himself is :

By the way I have also checked the book "Dust clouds in the middle east", that gives no idea about the crew names.
Thanks again
